Medi-Gas G210
Calibration
There are two types of calibration that the G210 unit requires; a zero and a span gas
calibration. The ‘zero’ calibration needs to be done prior to use on a daily basis and the
‘span gas’ calibration needs to be done monthly. The example gas in the Span Gas section
of the guide is O
2
. To complete these types of calibration please follow the below steps:
Zero Calibration: This type of calibration is to be completed with an N
2
provided by
Bedfont . Connect the cannister as shown in the diagram below.
1
Initiate the calibration by pressing Menu/ 3-Calibration/ 1-Zero with N

.
2
Turn the cannister on, then press the Pump button. Wait approximately 5 minutes and
then press the Start soft key to start the Zero calibration.
3
The monitor will read ‘Waiting for the gas to stabilise’. At this point you must wait
between 60-120 seconds for the gas to stabilise and then the monitor will show
‘Completed OK’.
4
To finish press Accept/ Exit/ Exit to take you back to the original dormant screen. The
monitor should now read 0ppm or 0% to show it has been zeroed.
Span Gas Calibration: This type of calibration is to be completed with the correct
calibration gas canister. The example gas given in this section of the guide is O

must be carried out in the same way with the other three calibration gases. This type of
calibration must be completed on a monthly basis. It is
strongly advised that you only use the gases supplied by
