Configuration
Configured via the COM 43 application.
Note related to manual calibration of the detectors connected to
an 8-analog input module.
1. Zero calibration
Inject standard gas to obtain 4 mA. Place the multimeter between points E
and D (Figure 24). If the value measured is different from 0 V, adjust C.
2. Sensitivity calibration
After injecting the gas, place the multimeter between points E and D
(Figure 24). If the value measured is different from 1.6 V, adjust B.
Should the adjustment value be different, calculate:
V= I (mA) x 0.10 (V/mA)
Example: If the current is 12 mA, “V” must be equal to 0.8 V.
If point E is not on the module use point G and add 1.2V to the measurement
