Commissioning and operating modes

The tasks described in this chapter should only be performed by authorized and
trained personnel as they are likely to jeopardize the reliability of detection.
This chapter describes:
• how to check the zero
• how to check the sensitivity
• the various operating modes

3.1 Purpose of control

Upon delivery, each detector has been tested and calibrated. There is normally no need for a
new calibration.
However, for safety, it is advisable to check the zero and the sensitivity as shown below.
The detector cover shall remain completely closed since the adjustments are carried
out through the window.
For flammable gas detector, we always recommend to calibrate the sensor with the
targeted gas. When the user wishes to calibrate the detector with a different gas,
refer to the table on page 30 for the use of recommended gas and corresponding
coefficient.

3.2 Necessary equipment

• Zero grade air cylinder
• Appropriate span gas cylinder (gas concentration should be between 30 and 70% of the
measurement range)
• Calibration cup (see Chapter
