The types of operating principle of ammeter are the rectifier type and the moving irontype, and the rectifier type ammeter has a merit of measuring small current valuecompared with moving iron type.

AC Ampere Meter

To deal with current exceeding 5A, use a 5A(1A) meter in combination with a C.T. A.C ammeter is used with a current transfomer externally mounted, and it is noted that primary current of a current transformer and a full scale of the meter are identical when used.If the circuit voltage exceeds 500V even when the current is less than 5A use a 5A(1A) meter in combination with a C.T to ensure insulation.The scale range of ammeter for motor circuit is extended up to 150%~500% of rated current,so that these are proteced from the impact of the starting current and ensured of long life.Am expanded scale has the normal maximum reading(upper limit of effective measurement range) at the app. 65% point on the scale, and the rest of it (65%~100%) is devoted toextension reading. (tolerance of extension area : 5%)

The types of operating principle of ammeter are the moving coil type.

DC Ampere Meter

For higher ranges than 5A, use external shunt with a 50mV(60mV) instrument.When D.C ammeter is used with a shunt, it is noted that a full scale and a terminalvoltage(50mV, 60mV) of the ammeter are same as the rated primary current and secondary voltage of the shunt respectively.Use any leadwire of which resistance is less then 0.05 in total.If the shunt lead resistance is indefinite, the meters may be set up with a availableresistor(V.R) for sensitivity adjustment.The shunt should be connected to the negative side linc.

Volt Meter

The types of operating principle of voltmeter are the rectifier type(A.C), and movingiron type(A.C) the voltmeter is used with a potential transformer externally mountedin case of high voltage.

AC Volt Meter

For higher ranges than 300V, use potential transformer(P.T) with a 150V A.C voltmeter. But the voltmeter of 600V is able to supply by order of customer.When lettering the voltage ratio on voltmeter, the meters for 3phase 4wire are lettered as likeas the meters for 3phase 3wire. namely on 3phase 4wire in case of the indicating for line-to-line voltage by line-to- ground voltage, and line-to-line voltage by line-to-line voltage, he meters are not wited the 3Full scale of voltmeter when use the P.T, the standard calibration value of voltmeters are 150V and/or 300V but, the full scale of voltmeters are indicated the 30Kv, 9000V, 4500V and 600V etc.

The types of operating principle of these meters are the transducer type,these meters measure reactive power.Transducer is used with the transducer type attached inside or outside.

Operating voltage range is 10% of rated voltage.For other voltage and/or current ratings higher then listed on the specification, use external C.T and/or external P.T with a 110V/5A instrument, when ordering, specify the full scale valuedesired, P.T ratio and C.T ratio.

Rating voltage of 3phase 4wire is at phase voltage.(/ 3 )The full scale of varmeter is generally 1/2, 1/3, or 1/4 of load capaciry.When using P.T and C.T, calibrating vars will be as follows

Namely 1) The standard calibration var of the meter for single phase 2wire : 300Var (0.3Kvar)2) Single phase 3wire : 500Var (0.5Kvar)3) 3phase 3wire : 500Var (0.5KVar)4) 3phase 4wire : 833Var (0.833Kvar)

The other 1) In case of 22900V- Calibrating var of 3phase 3wire : 480Var- Calibrating var of 3phase 4wire : 833Var2) In case of 380V- 3phase 3wire use to potential transformer ratio 380/110V : 579Var

not use to potential transformer : 2.0Kvar- 3phase 4wire use to potential transformer ratio

3) In case of 208 / 3Vno use to potential transformer at 3phase 4wire : 1.0Kvar

The standard scale is LAG. The varmeter with 0 point at center is recomended, if it is used instead of a power factormeter. In case of using the varmeter as a power factor meter, it is recommended, to use a leftside and of 0 point at the center as Lead-O-LAG.

The instrument of D-V T Type is self contained with the Transducer Box.

The types of operating principle of these meters are the transducer type and also the meter divide into the balanced power factor meter and theunbalanced power factor meter.

Operating voltage range : rated voltage 10%For other voltage and/or current ratings higher then listed in specification use external C.T and/or external P.T with a 110V/5A instrument.The instrument of D-P T Type is self contained with the Transducer Box.Rating voltage of 3phase 4wire is at phase voltage. (/ 3)The meter do not operate when load current is under 10% of rated current. And if the circuit current is less than a 1/3 of the ating (or less than 1.66A if the ratingis 5A) the error of P.F meter may have happened more than that of rated current.Standard scale : Lead 0.5~1.0~0.5Lag

Power Factor Meter

The types of operating principle of these meters are the transducer type.And this meter is used for measuring the frequency of generator.

Usable voltage range. 110V rating : 80V to 120V, 220V rating : 160V to 240VThe standard scale range is the 45Hz to 55Hz, and/or 55Hz to 65Hz.For a rating voltage higher than 220V, use external potential transformer with a 110V instrument.

This meter of complex type of analogue and digital type has a peak for memory ofmaximum instaneous value of the transient voltage orcurrent during the shortcircuit or ground fault on the transmission and distribution lines.

1. Normal voltage and current will be indicated by an along needle and then the peakvalue will be indicated on digital FAD(3Digital).

2. Demand of peak value will be indicated as memory (3Digital) the max one at only of many peak values.

3. The rating of digital is same as analogue and full scale of is same as on analogue.4. The peak value always turns on in the digital display, it is reset the peak value by

pressing the button.(push S/W)5. When auxiliary power loss occurs, the peak value will be accumulated in S-RAM.

when auxiliary power returns, the peak value will be displayed in the digital display.6. If an external reset terminal is connected on push button S/W, at inpossible

to reset on outside.

1. The LED display meter input value. To confirm the setting value amanual working condition is obtained by pushing the button as follow.

Other displays except input value return to the lnput mode after 6 secs.

How to adjust push S/W (see the picture No. ~ )

2. Operating value and operating time setting by pressing thebutton no and for 3secs at the same time, the setting mode will be entered the LED flashes then press

the button no to change the flashing value of the display anduse the button no to increase the count of it. After setting the input value, press the button no and for 3secs at the sametime to save the value of selection. (Display will be shown as below)

3. Meter Relay Operating This meter is able to set the time 0 to 99 seconds. If the input value is lower than low setting value or higher thanhigh setting value, the relay contacts are operated after presetting time.(During presetting time the LED or flashes, then afterpresetting time the LED is lightened and its replay is operated)When the auxiliary power is connected the initial time, low relaywill not operate without an input value which is higher than thelow setting value at first.(lt is to poeventing the operating therelay without input value at the initial)For turning off low relay operating set 0 to the low setting value.High setting value should be set higher than the input maximum value of meter to be off the high relay operating.

If a manual operation is not obtained for 6 secs while the LED isflashing, the LED will be returned to the input mode.
