 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
A test gas concentration of 20.93 % (air) would result in the following:
Output signal
0-10 V DC
Output signal
0-20 mA
4-20 mA
Note
 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.

The mA-signal depends on the set measuring range. Therefore, it is important to
check the correctness of the selected measuring range!
After calibration set the measuring range selection switch to desired measuring
range again.
The mA-output signal is dependent on the selected measuring range!
