level on reading device (RAW_VALUE in the payload) is 18.66 (x

*The calculation of A, B for the Ammonia gas sensor:
A = (0 - 25) / (-0.25 - 18.66) =1.32205
B = (y

) = (25 * (-0.25) - 0 * 18.66)/ (-0.25 - 18.66) = 0.33051
- User can use the off-line tool or downlink to write the values of A and B;
- Writing the new A and B successfully meant you had done the calibration process. Congratulation!
Do not use a damaged sensor. It must be repaired only by personnel authorized by the manufacturer.
Keep the sensor out of contact with aggressive substances e.g. acidic environments, which can react with metals,
as well as solvents, which may affect polymeric materials.
Diffusion holes of the sensor should be protected against the ingress of sprayed liquid or waterdrops.
The sensor is not intended to measure the target gas concentration contained in fluids.
Correct measurement is provided when the ambient temperature changes not faster than 0.6 °C/min.
Inspection and maintenance should be carried out by suitably trained personnel.
Persons, who have studied this UM, must be briefed on safety precautions when operating electrical equipment
intended for use in explosive areas in due course.
When dealing with a cylinder containing a gas mixture under pressure, it is necessary to follow safety
regulations.
There is no risk of pollution or negative impact on human health. The sensor does not contain any harmful
substances that may be released during its normal operation.
- Place the sensor in the area to monitor the target gas concentration. Please always check the gas molecular weight
v.s the air.
The factory default A = 1 and default B = 0
The RAW_VALUE in the payload is used for calibration
Step 4: Configure the new A and B into the device

flammable Gas Sensor
5. Installation notes
Notes:
* If a sensor has been kept in transport containers at temperatures below zero centigrade, leave it at +10...+35
°C for not less than one hour.
* if the Sensor is intended to install outdoors, please use a rain guard to protect the sensor from rain and direct
sunlight. Please
contact us to buy this accessory.
Note for Outdoor installation: For outdoor installation, please use the Rain guard to protect the sensor from
raindrops or snowflakes. Please contact us to buy the Rainguard.
