Calcmet Lite zero calibration.
–
An incorrect zero calibration is notified with a message printed in the screen:
"Background Signal Low!" (Please, read section “install CALCMETLITE.INI file”
in order to get further information concerning background check).
–
Trigger a continuous measurement by clicking START (check that the analysis
mode is enabled). The point is to check that, after zero calibration, the analysis
results are around 0 (if the sample cell is still purged with zero calibration gas).
Pump needs to be deactivated when you check the zero calibration otherwise
sample gas will enter the sample cell and zero results are invalid.
–
After a successful zero calibration, sample measurements can be performed.
The sample pump is switched on when continuous measurement is started if
pump mode is activated in Settings
