iTo keep the approvals the cable gland always has to be considered! Depending on thecable type choose the according cable gland. If you design the detector line as a stubevery detector has to be closed with the blind gland at the non used cable entry.

1.2 Calibration of DP60/64

Part of the commissionin of a gas detector is the calibration procedure. On a CC60 we de-fine two types of calibration modes:

New calibration (or first cali-bration)

This is the calibration done when the detector is com-missioned for the first time or if a sensor has beenchanged.

Recalibration This is the procedure done every time you calibrate adetector which has been already commissioned once,until you change the sensor.

For a proper calibration following points have to be considered:

Calibration gas: 2.64% methane (CH4) in synthetic air = 60% LEL

Flow rate: 0.5 – 1 l/min

Exposure to gas: 1 min

If zero gas has to be used:

Zero gas: Synthetic air (20% Oxygen O2 + 80% Nitrogen N2)



i If you calibrate on a CC60 please note that you have to follow exactly the times givenabove. If not, the CC60 won’t accept the calibration.

1.2.1 New calibration (or first calibration)

Conditioning time: at least 30 min

Detector signal default (I0): < 5 mA

Minimum required signal increase: 5 mA

iIf a sensor cannot reach the minimum required signal increase it has to be changed.With standard programming the CC60 unit doesn’t allow to store the calibration data ofsuch a detector. For special cases you can use the sensor code 99 (Tool G60 5min 2mA).

1.2.2 Recalibration

If the deviation of the display of the concentration varies more than 10% you have to recali-brate the detector. At least, it is recommended to do such a recalibration every 12 month.

1.3 Programming of the system for DP60/64

1) Because of the risk of poisoning of the Pellistor due to compounds contained in biogas, we recommend to use the DO61–02 instead.

If another calibration gas is used or another application is requested please conctact CE–CH.

1.4 Change of the sensor

If the loss of signal since the commissioning day is >30% (means that the actual signal in-crease is <70% of the signal incrase at commissioning) than the sensor has to be replaced.

On sensor change you must execute a new calibration! On a CC60 you first have todelete the old calibration data (with F4 160 ––> OFF) before starting the new calibration.

1.5 Remarks to DP60/64

Life time The sensor life time is reduced if lead, halogens, sulfur compounds or silicones affect thesensor.

Positioning The mentioned indications are generally given. For special cases the positioning of the de-tector can vary.

4) Up to Version 5.17 (1.05–17), semiconductor detectors where programmed on a CC60 with code 99 (Tool: G60 5min 2mA)!5) The values given are the values which have to be programmed on the unit. The corresponding concentration in ppm is given below.

Differing programmings have to be discussed with CE–CH.Because of its non–linearity a semiconductor sensor cannot display a quantitative va-lue according to the concentration measured on site. The concentration displayed cor-responds only at one point to the effective value on site (e.g. at the alarm point). Werecommend therefore to label only the thresholds Warning, Prealarm and Alarm wi-thout any mention to the concentration value. Important: The displayed values are not ppm’s! You can describe them better as scaling units or display units!



On sensor change you must execute a new calibration! On a CC60 you first have todelete the old calibration data (with F4 160 ––> OFF) before starting the new calibra-tion.

4.2 Calibration of DE60/64





For the calibration of electrochemical sensors they can be divided into two different groups,depending of the time of calibration needed:– for the first group following data is given:


DE60/64–02: CO 500 ppm carbon monoxide (CO) in synthetic air

DE60/64–03: H2S 25 ppm hydrogen sulfide (H2S) in synthetic air

DE60/64–05: SO2 50 ppm sulfur dioxide (SO2) in synthetic air

DE60/64–06: NO 50 ppm nitrogen monoxide (NO) in nitrogen (N2)

DE60/64–07: Cl2 20 ppm chlorine (Cl2) in synthetic air (or nitrogen)

DE60/64–09: HCN 50 ppm hydrocyanic acid (HCN) in synthetic air

DE60/64–12: H2 1000 ppm hydrogen (H2) in synthetic air

DE60/64–21: N2 Nitrogen (N2) 100%



– for the second group following data is given:


DE60/64–08: NO2 20 ppm nitrogen dioxide (NO2) in synthetic air

DE60/64–10: HCl 50 ppm hydrogen chloride (HCl) in synthetic air (or N2)

DE60/64–11: NH3 60 ppm ammonia (NH3) in syntheic air

DE60/64–13: C2H4O 20 ppm ethylene oxide (ETO) in synthetic air









Conditioning time: at least 2 h


Minmum required signal increase: 2 mA for NH3 and ETO–sensor4 mA all other types

iThe conditioning time has to be kept. Some sensors are delivered with a bias–battery on it. If this battery is low or missing,the sensors have to be connected to a control unit for at least 48h. Do not start the cali-bration before the detector signal default (I0) is <4 mA.

4.2.2 Recalibration


4.2.3 Calibration of oxygen detectors (DE60/64–21)

The calibration of oxygen sensors can be done as follow (see also drawing below):� CC60

– Oxygen displacement (O2–removal)After having started the calibration � wait at least 1 min before applying the calibrationgas �. Apply the calibration gas (nitrogen, N2) to the sensor for exactly 3 min �.

When you program a oxygen detector for the monitoring of oxygen displacement it’svery important that you program the sensor (and the bargraph) as invers (see alsosection 4.3).

– Oxygen increase monitoring (O2–increase)After you start � the calibration apply the calibration gas (nitrogen) for at least 4 minbevore you remove it for 3 min �. After this 3 min you must reapply the calibration gas(nitrogen) for at least 3 min �!

8.3 Use of calibration factors (exemples)

Calibration factors are used whenever a detector is calibrated not with the substance todetect but with another type of gas, e.g. a reference gas. Cerberus uses 2.64% methane inair (corresponding to 60% LEL) as reference (K–factor = 1).

To calculate the correct calibration concentration to program you can use following formula(all the concentrations are given in % LEL of the corresponding substances):

Concentration(calibration gas) * K–factor(gas to detect) � K–factor(calibration gas)

8.3.1 Exemple 1: Detection of hexane, calibration gasmethane (Cerberus reference gas)

If you have to calibrate a Pellistor (DP60/64) with 60% LEL methane for the detection ofhexane you have to program following concentration:

60% UEG * K–factor(hexane) = 60% LEL * 2.5 = 150% LEL

This programming means, that 150% LEL hexane produce the same signal at the detectoras 60% LEL methane do. If you test for example such a sensor with 60% LEL methane youwill get a display of 150%. If you test it with 50% LEL hexane you will get also 50% displayed(± measuring error).

8.3.2 Exemple 2: Detection of hydrogen (H2), calibration gaspropane

If you calibrate a Pellistor (DP60/64) wtih 50% LEL propane to detect hydrogen (H2) youhave to program following concentration:

50% LEL * K–factor(hydrogen) ÷ K–factor(propane) =50% LEL * 1.4 ÷ 1.7 = 41% LEL

This means, that you need ’only’ (relative, related to %LEL) a concentration of 41% LEL ofhydrogen to get the same signal at the detector as with 50% LEL propane!

iThe proper calculation of the calibration concentration to program is very important asit is neccessary for the correct functioning of the system. If there are any unclearnes-ses please contact your local gas specialist or CE–CH directly.

10 Glossary

Bias battery The bias battery is used for the preconditioning of electrochemical sensors. Its battery sup-plies a bias current, preparing the sensor for the use at the shortest possible time. The sen-sors which require a conditioning period are normally delivered with this bias battery.

Conditioning time The period required to prepare an electrochemical sensor for use. The sensor must eitherbe connected to the unit while it is running, or be pre–conditioned by the bias battery

Detector signal default The current delivered by a gas detector, when no gas concentration is detected at the sen-sor.

Calibration current The current delivered by a gas detector , when the calibration concentration is detected atthe sensor.

TLV/TWA The Threshold Limit Value/Time Weighted Average is the concentration to which a personcan be exposed for eight hours a day (within a week of 40h) without danger to health.

STEL The Short Term Exposure Limit is the concentration, which can not be exceeded for morethan 10 min for one time during a day.

IDLH Immediately dangerous to life or healthA person must not be exposed to the given concentration for more than 30 minutes.

Calibration factor The calibration factor can be used for calibration of gas detectors for flammable gases andliquids. Because of the different cross sensitivity of the detectors the calibration factor isused to set up those detectors according to the desired application.
