Calibration example for the O
2
sensor:
•
Calibration will only be possible if the sensor status is set to" ----" (cell that has never had an on-site calibration) or
"inactive".
•
Apply the gas to the instrument and adjust the gas outlet pressure of the cylinder so that the flow meter indicates a minimum flow rate
of 0.5 l/m : this ensures that the instrument takes up exactly the amount of gas required by the internal pump.
•
The instrument measures the concentration of the standard gas;
otherwise wait at least 3 minutes for the reading
to stabilise.
The reading is displayed in the
"Measured gas
" line.
Zeroes the timer -
helps to keep the
stabilisation
period under
control.
