Test after replacing the sensor.
Reconnect the power, the probe starts blinking to the waiting time (Warm-up).
After waiting you can proceed to test the functioning inputting the sample gas.
WARNING !! From this moment on for all the duration of 24 hours of self-calibration, the probe must stay in
clean air without loss of GAS.
The probe continues to blink at a low frequency again for 24 hours to make sure that the probe do the auto
calibration.
Before performing this operation disconnect the power to the probe

The installation of the SGM595 probe, its ordinary and
extraordinary maintenance, and its out of service removal
at the end of the functional life guaranteed by the
manufacturer, must be carried out by authorized or
specialized personnel.
The general test should be performed by issuing gas from
a pre-calibrated aerosol within the percentages illustrated
on the side.
Important:
This test must be carried out at least once a
year.
