Performance Procedures

Testing the Monitor  

If the pump in the CO2 module is replaced, the Pump Operating Time counter should be reset 
to start counting operating time for the new pump.

When the Pump Op Time has been reset a "CO2 Equipment Malfunction" INOP will be 
generated on restarting the monitor. To clear this INOP you must perform a flow check and 
store the flow in Diagnostic Mode (select Store Flow). 

1

Reopen the 5% gas valve and allow the value to stabilize.

2

Check that the value displayed on the monitor is correct and within the tolerance 
(see Step 2 in above section).

3

Disconnect the 5% calibration gas and connect the 10% calibration gas.

4

Open the valve on the flow regulator to allow 10% CO

2

 gas to flow into the 

monitor. Allow the value to stabilize.

5

Check that the value displayed on the monitor (X7) is correct and within the 
tolerance (see Step 6 above). If one or both values are not within tolerances, the 
CO

2

 module must be exchanged.

1

In the CO2 Test menu, select Pump Op Time.

2

Select Reset to Zero.
