Calibrating The Sensitivity For An Individual Measuring Channel - Drager X-am 5000 Technical Manual

Calibrating the sensitivity for an individual measuring channel


The span calibration can be carried out specifically for individual sensors.

In the case of the span calibration, 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:
Ex: 40 to 100 %LEL
O : 10 to 25 vol. %
2
CO: 20 to 999 ppm
H S: 5 to 99 ppm
2
NO
: 5 to 99 ppm
2
Test gas concentration of other gases:
refer to the Instructions for Use of the
respective DrägerSensors.

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).
CAUTION
Health hazard! Do not inhale the test
gas. Risk to health!
Observe the hazard warnings of the
relevant Safety Data Sheets.

Switch on the device and insert it into the calibration cradle.

Press and hold the [ + ] key for 5 seconds to call the calibration menu, enter the
password and select the single gas calibration function, page 20.

Press the key to start the channel
OK
selection.

The display flashes the gas of the first
measuring channel, e.g., » Ex -
%LEL «.

Press the key to carry out the
OK
calibration of this measuring channel,
or

Use the key to select another
measuring channel (O
- ppm or CO - ppm).
