
Check the analog output signals;

The signal to be measured can be calculated as follows:
(max. signal output - min. signal output) x Concentration [%]
Measured value =

+ min. Signal output
Full scale value [%]
A test gas concentration of 20.93 % (air) would result in the following:
Output signal Signal to be measured with full scale value
100 %
0-10 V DC 2.09 V
Output signal Signal to be measured with full scale value
30 % 100 %
0-20 mA 13.95 mA 4.19 mA
4-20 mA 15.16 mA 7.35 mA
Note
The mA-signal depends on the set measuring range. Therefore, it is important to
check the correctness of the selected measuring range!

Shut-off the output valve of the pressure regulator and the bottle valve and disconnect the tube connec-
tion to the analyzer.
The full scale value calibration has been completed.
Attention
After calibration set the measuring range selection switch to desired measuring
range again.
The mA-output signal is dependent on the selected measuring range!
