Span Calibration - MSA ALTAIR 5X Manuel D'utilisation

Span Calibration

To skip the Span calibration procedure, push the  button.
If the SPAN calibration of the combustible sensor is skipped after a successful ZERO
calibration, the combustible sensor reading may be replaced with a moving display of
"PLEASE WAIT" for a few moments. This is normal, and the device is fully operational
once a combustible gas reading reappears.
If no button is pushed for 30 seconds, span calibration is skipped.
Because of the different possible combinations of gases that are possible, skipping a Span calibration
could advance the user to the Span calibration of another installed sensor, or back to Measuring mode.
When calibrating with combustible gases > 100 % LEL, select the "Yes" option to prompt "Span Cali-
bration?" BEFORE applying gas to the device.
(1) Connect one end of tubing to the cylinder
regulator (supplied in the calibration kit).
(2) Connect the other end of the tubing to the
pump inlet.
(3) Press the  button to calibrate (span) the
device.
