Calibrating/adjusting the sensitivity for an individual measuring channel
— The span calibration/adjustment can be carried out specifically for individual
sensors.
— In the case of the span calibration/adjustment, the sensitivity of the selected sensor
is set to the value of the test gas used.
— Use a standard test gas.
Allowed test gas concentration:
Connect the test gas cylinder with the
calibration cradle.
Vent the test gas into a fume
cupboard or into the open air (with a
hose connected to the second
connector of the calibration cradle).
