The measuring range in which the calibration is to be performed is shown in brackets next
to the current measuring range. In Fig. 75, the current measuring range is “4” and the mea-
suring range of the calibration is “1”.
The test gas concentration, here “0.00”, is shown above the green arrow on the right hand-
side at the bottom of the screen. The green arrow is pointing at a calibration range of “-5.0
to +5.0 vol%”. The value of the actual gas and the test gas concentration needs to be in this
predefined measuring range.
To adjust the calibration range or test gas concentration, please tap on the edit button.
The M4/S2 screen opens with the channel-specific parameter “3 = Calibration/Adjust-
ment”. Here you can enter the parameters of your test gas and change the calibration
range.

Please set the values to meet your calibration requirements. After adjusting the parame-
ters, please tap on the Calibration button M5 to confirm your entries.
