Carbon Monoxide (CO) Gas Detector

COWJuly 18General Notes
1.

High density of some other gasses may effect the reading.

2.

Observe maximum permissible cable lengths.

3.

If cable runs parallel to the mains cable: Use shielded cables.

4.

Never test with flammable gasses.

5.

The cable entry always should have to be pointing downwards.

6.

The data indicated under ‘Technical Data’ apply only to vertically mounted transmitters.

7.

Duct type transmitters should be far away from humidifiers, min. 2 meters. (duct version on request).

8.

Room and Wall type transmitters should have to be mounted in the center of wall but not near to any windows (room version on request)

Cross Sensivity
The values given are only for information and should not be used as a basis for cross calibration.
Cross sensivities may not be linear and should not be scaled either.
Datas based on gasing for 5 minuttes using test equipment.

Carbon Monoxide (CO) Gas Detector

COWJuly 18Calibration

1.. 6 months of stock life needs nearly 10 minutes of working at fresh air for settling the baseline.
2.. SPAN Calibration can be done one by one for 0ppm, 50ppm, 100ppm and 300ppm for best performance.
3.. 0…50ppm, 50…100ppm and 100…300ppm ranges have independent calibration maps.
4.. Besides calibrating the max. range that will used, please make calibration for lower ranges.
5.. Before any calibration, check CONFIG Jumpers and set to calibration level.

Calibration - 0ppm, 50ppm, 100ppm, 300ppm
1.. Open the cover and power the detector, do not close the cover during process,
2.. Wait for min. 3 minutes for warming up the sensor,
3.. Use right CO Calibration Gas according to Jumper Settings, 0ppm, 50ppm, 100ppm or 300ppm,
You may use Fresh Air for 0ppm calibration (which is lower than 1ppm CO),4.. Apply the gas for min. 2 minutes with 0.5 lt/min. flow rate,
5.. Keep pressing for min. 10 seconds to SPAN (MENU) button, LED will light continuously,
6.. When LED gets OFF, take your finger from the button,
7.. LED double flashes during ZERO process for 10 seconds,
8.. The calibration point is an average of 20 measurements between 5th and 10th seconds,
9.. LED lights continuously for 3 seconds,
10..Gas Detector turns back normal condition and works with new calibration setting.

Calibration - Factory Reset
1.. Keep pressing for min. 10 seconds to ZERO button, LED will light continuously,
2.. When LED gets OFF, take your finger from the button,
3.. LED flashes continuously during RESET process for 10 seconds,
4.. LED lights continuously for 3 seconds,
5.. Gas Detector turns back normal condition and work with factory calibration settings.
