TM 5-6675-330-12&P
System ConfigurationThe AutoRanger @ IIx EDM instrument is a lightweight,compact unit designed for convenient tribrach moun-ting (see Figure 4), The integral yoke azimuth base pro-vides a convenient set-up for distance measurementsonly.
Operating power for the AutoRanger o IIx EDM instru-ment is supplied by a compact, 12-volt battery unit, Anauxiliary power cable which permits operation of theinstrument from any convenient 12-volt DC powersource, such as a lead-acid battery, is also supplied,
The instrument uses a current modulated, solid state,light-emitting diode as a light source, The light beammodulating frequencies are generated by an internalquartz-crystal oscillator, which has a stability of f 1ppm to assure measurement accuracy, An audiblesignal indicates when the invisible [infrared) light beamis on target,
Automatic Display Updating
With the instrument set to range mode, the 8-digitnumerical display is continually updated approximate-ly every 6 seconds. A rodman can move backward orforward with the retro-reflector, and the instrument willdisplay the new distance automatically. Momentary in-terruptions of the light beam by traffic, atmosphericdisturbances, wildlife, etc., will not affect the ranging
sequence or accuracy of the distance measurements.Slope distance readouts are provided directly inmeters and must be converted to horizontal distancesfor survey computation.
Simple Operation
After sighting the instrument onto the retro-reflector andmaximizing the return signal, the operator performs thefollowing simple steps,
a. Presses calibrate switch.b. Waits for Ready Light.c. Switches from the aim mode to the range mode
by pressing a switch
The AutoRanger m IIx EDM instrument is designed foroperation with an on-board battery unit, Two batteryunits are supplied with the instrument. Approximately750 continuous measurements can be made fromeach battery before recharging is necessary, A batterycharger is supplied which is capable of charging bothbatteries at the same time.

OPERATING PROCEDURES
Operating Instructions
1. Preliminary Set-up
(a] Set up tripod and plumb accurately over thepoint from which the distance measurement is tobe made.
I NOTE:Set up over the point very carefully; Inaccurate set-up is usually the cause of measurement errors. I
(b) Adjust the tribrach leveling screws as requiredto center the tribrach leveling bubble, Make theleveling adjustment accurately. Remove theodoliteand mount instrument on tribrach. Check tribrachleveling bubble; readjust if necessary.
(c) Adjust vertical lock (14) and horizontal lock (19)firmly enough to allow holding action, but freeenough to permit movement of the instrumentunder pressure.
(d) Place battery pack into instrument (21) or us-auxiliary power cable connect to remote 12vdcpower source.
12 Figure 6- Controls
TM 5-6675-330-12&P
(e) When using the auxiliary cable, connect thepower cable to power connector (2). Connect thered clip lead of the power cable to the positiveterminal of the 12 volt DC power source, and con-nect the black clip lead to the negative terminalof the DC power source.
(f) Setup the retro-reflector accurately over thepoint to which the distance measurement is to bemade. Align the retro-reflector on the line of sightto the instrument (see Figure 7). For maximumsignal return the retro-reflectors should be perpen-dicular, with *5 degrees, to the instrument line-of-sight.
Figure 7- Prism Alignment
2. Computing PPM Correction
[a) Take a temperature reading with the ther-mometer placed in a shaded area and positionedsix to eight feet above ground surface. Record thistemperature reading.
(b) Take a barometric reading with the barometerplaced in a shaded area that is protected fromgusty wind conditions. Record this barometricreading,
(c) Using the Atmospheric Correction Graph (SeeFigure 8), Page 17, read the PPM Correction at theintersection of lines extending from the measuredtemperature and pressure, A one PPM variation willcause a 1 millimeter per 1 kilometer distancevariation.
(d) Using PPM switches (43), dial the computed PPMcorrection into the instrument.
NOTE:The computed PPM correction can be eitherpositive or negative. Remember that the * sectionof the PPM switch (43) will have to be set to one ofthe positive or negative position for positive ornegative PPM corrections, respectively.
3. Offset Switch Setting
(a) Obtain the instrument total offset correction(TOC) from the instrument offset plaque located atthe bottom front of the instrument. (Page 18].
13
TM 5-6675-330-12&P
[b] Using OFFSET switches (5), dial the offsetcorrection into the instrument.
4. Test
An automatic test function is built into theinstrument, The test provides a quick check of theinternal microcomputer and display circuits, Toperform a test, proceed as follows:
(a] Press PWR switch (3) to turn on the instrument.(b] When power is turned ON the instrument entersthe test mode, and the numerical display (7)should sequence automatically from all zeros to allnines and then display four zeros.
5. Target AcquisitionNOTE:
Maximum range accuracy can be achieved onlyif the instrument is positioned accurately on target.
After the test function has been completed, theinstrument is ready for alignment on the retro-reflector target. Using the vertical (17) andhorizontal (20) tangent screws, position the sightingscope reticle on the target. For shorter distances
Figure 6- Controls w
f? U.S. GOVERNMENT PRINTING OFFICE lSSS-SS4.1WS716 14 Change 1
TM 5-6675-330-12&P
the sighting point should be 4.5 inches above theretro-reflector. When the retro-reflector is firstacquired and a return signal is received, an audiotone will sound for approximately two seconds andthen go off. The audio tone will be reinitiated eachtime the return signal falls below a predeterminedlevel after initial acquisition. When the retro-reflector has been acquired, proceed as follows:
(a) Note the indication on SIGNAL meter (6).Carefully adjust the vertical and horizontal tangentmotions as required to maximize the SIGNAL meterindication.
(b] If the pointer of SIGNAL meter (6) runs upagainst the right stop because the signal level istoo great, press CAL/START switch (12). READY light(16) should light and the meter pointer should bepositioned automatically to approximately mid-scale before further adjustment of vertical andhorizontal tangent motions is attempted, Nearmaximum range of instrument the meter pointermay indicate left of center, but, if READY light is on,target acquisition may continue.
6. Ranging
(a) After the target acquisition procedure has beencompleted, press AIM/RANGE switch (18), beingvery careful not to move the instrument, AIM light(15) should go out.
(b) The instrument will begin to cycle automatically,A slight clicking sound will indicate that themeasurement is being made, In approximately sixseconds, the measured range will be displayed onnumerical display (7) Read the range directly, inmeters, The instrument will continue to make rangemeasurements automatically, updating the rangeindication on numerical display (7) approximatelyevery six seconds as long as the instrument remainsin the range mode. Readings may vary by a fewmillimeters at short distances to several millimetersat long distances.
NOTE:The audio tone will not function in the range modeof operation.
(c) Repeat steps (a) and (b) until no further in-crease in the indication on SIGNAL meter (6) canbe obtained.
(d)As the last step in the acquisition procedure,press CAL/START switch (12) and wait for READY Iight(46) to light. When the READY light lights, the instru-ment is ready for ranging.
(c) When in the range mode, pressing theCAL/START switch will initiate a range sequence.
(d) The range sequence may be stopped by press-ing the AIM/RANGE (18) switch to select the aimmode or by pressing the PWR (3) switch to turn offinstrument power.

Opera t ing Notes
The following information facilitates rapid and pro-per use of the instrument. Since the distancemeasurement process is completely automatic, theseoperating notes are intended to provide clarificationOf the instrument set-up procedures. The informationincluded here is particularly important when eithera new instrument is to be used for the first time, orwhen an operator desires an initial familiarizationwith the instrument.
1. Mount ing.The instrument is designed for mounting on atripod-mounted theodolite tribrach. If the tribrachtype is changed, a different mounting adaptermay be required.
2. Retro-reflectors (Prisms)
Since an offset correction can be dialed manuallyinto the instrument, the instrument can be used withany prism whose reflection constant is known. Thesupplied prism assemblies and adapters aredesigned for mounting on a tripod-mountedtheodolite tribrach.
3. Instrument and System Offset.
The true distance between the vertical axis of anEDM instrument and the vertical axis of a retro-reflector usually differs from the uncorrecteddistance computed by the EDM instrument. This dif-
16
ference is due to a combination of the retro-reflector prism offset and the instrument offset. Priorto shipment of each AutoRanger o Ilx EDM instru-ment an offset correction, calibrated for that instru-ment and a standard 30mm retro-reflector prism, isentered into the instrument using the offset swit-ches. The total offset correction (TOC) is stampedon a decal affixed to the bottom-front of the instru-ment. As long as retro-reflector prisms of the sameoffset are used with the instrument, and the offsetswitch settings are not disturbed, the display rangeof the AutoRanger 0 Ilx EDM instrument will corres-pond to the true range, with no need for operatorentry of offset corrections.
4. Br ight Sun Caut ion.
Optical systems for EDM equipment are designedfor infinity focus. The sensitive detector is located atthe focal point of the receiver optics. Do not aimthe instrument directly at a bright sun.
5. Ready L ight.
High accuracy is maintained in theAutoRanger ® 11x EDM Instrument through use of awindow circuit that automatically monitors theranging signal. This circuit permits range com-putations only when the return signal is withinpreset limits. When the target has been properlyacquired and the CAL/START switch is pressed, aninternal servo system, automatically adjusts an op-tical attenuator as required to bring the signallevel within the proper operating limits. Proper ad-justment of return signal level is indicated byIighting of the READY Iight.

Atmospheric Correction. the graph (see Figure 8). Enter the graph at a
Because the velocity of light in air varies slightlywith different atmospheric conditions, an at-mospheric correction is required for local condi-tions if the full accuracy of the AutoRanger @ IIxEDM instrument is to be attained. The main at-mospheric factors affecting light velocity are airpressure and temperature; humidity changes havea negligible effect.
The atmospheric correction should be taken from
known pressure and temperature and read the at-mospheric constant (in parts per million), This valuemust be entered into the EDM instrument to obtaincorrected distance measurements.
When measuring long lines or lines having differentelevations at the end points, measuring thepressure and temperature at both ends of the lineand averaging the values provides a more ac-curate atmospheric correction constant. 17
TM 5-6675-330-12&P
7. Power Fuse. 9. Determination of Total Offset Correction.
The power circuits of the instrument are protectedagainst overload by a power fuse. If the powerfuse should fail, power is no longer applied to theinternal circuits, If no response is seen when thePWR switch (3) is actuated, check or replace fuse,If more than one fuse failure occurs, the instrumentshould be returned to depot repair facility forrepair.
8. BATT Light.A low battery condition is indicated by flashing ofBATT light (4). Reliable range measurements canstill be made with the light flashing; however, theinstrument will go into an automatic power-offmode when battery voltage falls below a presetlimit. At this point, the BATT light will glow brightlyand steadily, Connection of a fully charged bat-tery pack or auxiliary source to the instrument willpermit resumption of normal operation.
NOTE:Under low ambient light conditions a faint glowmay be observed, This is normal and does not in-dicate a low battery voltage condition,
Although the total offset correction has beenentered into the instrument before shipment fromthe factory, the accuracy of the total offset shouldbe verified under actual operating conditions.(Refer to performance Check,) If no known baseline is available, use the following procedure.
The true distance between the vertical axis of anEDM instrument and the vertical axis of a retro-reflector will usually differ from the instrument’sdisplayed range unless the proper offset correctionfigure is used. The difference is due primarily totwo factors: retro-reflector prism offset, andinstrument offset.
A prism offset is positive (the effect of the prism is toincrease the indicated range beyond the truevalue),
If a known base line is not available fordetermination of the ranging accuracy of theinstrument, the following peg test may be used todetermine the total offset correction required:
NOTE:For optimum results make A=60m * 1m,B=40m* 1m, and C= 100m* 1m, or multiplesthereof.

(a] Lay out three points in a straight line, Thesepoints do not have to be on a level plane, but theyshould be on a uniform grade, The intermediatepoint should not divide the line into two equalsegments.
Figure 9- System Offset Correction Test Layout
(b) Set the offset (5) ppm (13) switches on the frontpanel to 00.
[c) Set up the instrument on each of the threepoints and make measurements to each of theother points. This gives double measurements forboth segments of the line and for the overalllength; that is, one measurement will be madefrom each end of each line, Use the mean of thetwo measurements in the calculation. Allmeasurements consist of the mean of tenindividual range displays on the instrument.
[d) Compute the total offset correction, using thedesignations in figure 9 and the followingequations,
C = A + B
MA = Mean distance read for Segment A
MB = Mean distance read for Segment B
MC = Mean distance read for Segment C
Then:
TOC = MC –(MA+MB]

If the peg test has been run to verify the TOC asstamped on the instrument (assuming the use of30mm prisms), verify or change accordingly.
If the peg test has been run to establish the TOCusing other than 30mm prisms, the new TOC shouldbe used in place of factory established TOC.

Basic Principles of OperationThe AutoRanger @ IIx EDM instrument uses a techniquetypical of EDM systems, known as phase comparison(Figure 11). The modulated light beam is directedonto a retro-reflector positioned at the point to whichthe range measurement is to be made, A reflectedlight beam returns from the retro-reflector to theinstrument, where it is converted into an electricalsignal (Figure 12), The phase relationship between thetransmitted and reflected beams of light is comparedby the unit’s self-contained computer processingcircuitry, and is converted into a direct read-out ofslope distance. Figure 13 shows a simplified blockdiagram of the AutoRanger@ IIx EDM instrument.

Effects of Prisms and Atmosphere on
Cube corner prisms, normally the type of reflectorused as a target for light emitting instruments, havethe property of reflecting light rays back in the samedirection as the incoming rays. This eliminates criticalangular alignment with respect to the EDM instrument,The quality of the prism, defined by the flatness of thesurfaces and the accuracy of the 90 degree angles,and the total number of prisms have a square laweffect on the maximum distance that can bemeasured. For example, decreasing the quality of theprisms ‘-y a factor of two increases by a factor of fourthe number of prisms required to give the samemaximum range, or, for a given quality prism,doubling the range would require a factor of fourincrease in the number of prisms required.Atmospheric factors such as absorption, scattering,refraction, and background radiation tend to reducethe maximum distance that can be measured.Absorption and scattering relate to particles such asdust, fog, smoke, rain/snow, etc., in the air and havethe effect of reducing maximum range in anexponential manner. This atmospheric condition isnormally defined in terms of sea level visibility and,for a given number and quality of prisms, can causewide variations in the maximum range achievable.
Variations in atmospheric pressure and temperature,which cause localized changes in the index ofrefraction of air, result in the bending of light rays andcan cause a reduction in range capability for agiven number of reflector prisms, These localizedvariations are generally described as scintillation orheat shimmer and are more pronounced along lineshaving low ground clearance, As a general rule,high scintillation conditions can be considered as asquare law function, thus requiring four times thenumber of prisms to double the range, Light raybending due to more gradual gradients in the indexof refraction, especially over long ranges, can resultin an apparent change in a target’s position, This, inthe case of low ground clearance along a measuredline, could result in the loss of a target when goingfrom daytime to night time conditions, Back-groundradiation, in the visible and infrared wave lengths,has the affect of increasing electronic noise internalto the instrument and may cause wide variations inreadings for a given distance, This condition normallyexists only when working with the EDM instrumentpointed close to the sun and should be avoidedbecause of possible damage to internal instrumentcomponents.

SECTION IVMAINTENANCEPackaging
The instrument is packaged in a molded carryingcase with foam inserts. [See Figure 3). Pack theequipment in the carrying cases when it is not in use.
TransportationThe carrying case has been designed to minimize thepossibility of damage to the instrument and theaccessories when they are being transported. Makesure that all equipment is properly packed in thecarrying case. Protect the equipment from shock andvibration to the maximum extent possible while it isbeing transported.
ShipmentPackaging for shipment requires special attentionbecause shipped items may be handled roughly.When shipping the instrument to an authorizedservice center for repair, ship only the instrument in itscarrying case.
The carrying case is not a shipping containerEnsure that the carrying case is packagedadequately for shipment to prevent damage.
Lens CareUse care when cleaning dust or moisture from lenses.Do not touch with fingers or use coarse cloth, paper,or other material that might scratch the lenses. Tissue,or a camel’s hair brush may be used. Although rarelyrequired, mild soap and water solutions may be usedsafely for the removal of fingerprints.
Condensa t ionCondensation of moisture on the instrument lensescan occur when the instrument is taken from a coldenvironment to a warm environment, such as fromoutdoors to indoors. It is recommended that theinstrument be left in its carrying case for several hoursunder such conditions to allow for a gradualt e m p e r a t u r e c h a n g e .
Retro-Reflector Prism CareThe retro-reflector prisms are high-quality opticalprisms, and should be given the same care asrecommended for lenses.
LubricationThe threads of the yoke tangent and locking screwsare the only items that may require lubrication.Application of a small amount of dry lubricant (suchas graphite) to the threads will be sufficient in mostc a s e s .

Nickel-Cadmium Battery1. The power unit consists of a unitized, 12-volt,
NiCad battery package. A battery charger issupplied with the instrument for recharging of thebattery pack after each normal day of operation,and after prolonged periods of storage. Thebattery charger has been designed for an “over-night” charge.
2. A NiCad battery has been selected for use in thepower unit, because such a battery, underproper care, provides good performance overan extended lifetime. The following information isprovided to assist the user in obtaining optimumbattery performance.
3. Temporary effects on battery capacity may occurif repetitive discharge and charge cycles areused. This is sometimes referred to as “memory.”When the battery is fully discharged ordischarged to random levels as in normaloperation and charged for random times, thismemory effect does not occur.
CAUTIONBefore plugging the battery charger into an ACpower outlet, make certain that the rating of thebattery charger matches the rating of the available
I AC Power source.
4. The battery charger is designed to operate froma nominal 110 volt, 50/60Hz supply. When only a220 volt 50/60Hz source is available, use thesupplied 220/110 volt adapter.
TM 5-6675-330-12&P
Charging Procedure1. To charge the battery unit:
(a)
[b)
(c)
Plug the battery charger into an AC poweroutlet that is continuously supplied withpower.
Plug the connector end of the batterycharger cable into the power connector onthe battery unit, The battery charger containsred charge lights, which indicate that thepower unit is taking a charge.
A fully discharged battery unit requiresapproximately 16 hours to completerecharge, using the supplied battery charger.
2. The battery unit may be left plugged into thebattery charger without danger of overcharging;however, during prolonged periods of inactivity,the battery charger should be disconnected fromthe battery pack and stored,
3. To prevent possible damage to the NiCadbattery, the battery unit should never be chargedin an area where the temperature falls below 5°C(40°F), The ideal temperature range for chargingis 5°C (40°F) to 27°C [90°F].
NOTEWhile the battery unit is charging, the battery charger maybecome warm to the touch and may emit a buzzingsound, This is normal, and is not an indication of amalfunction in the battery charger I

This fine document...
Was brought to you by me:
Liberated Manuals -- free army and government manuals
Why do I do it? I am tired of sleazy CD-ROM sellers, who take publicly available information, slap “watermarks” and other junk on it, and sell it. Those masters of search engine manipulation make sure that their sites that sell free information, come up first in search engines. They did not create it... They did not even scan it... Why should they get your money? Why are not letting you give those free manuals to your friends?
I am setting this document FREE. This document was made by the US Government and is NOT protected by Copyright. Feel free to share, republish, sell and so on.
I am not asking you for donations, fees or handouts. If you can, please provide a link to liberatedmanuals.com, so that free manuals come up first in search engines:
