6WHS Select the value for the calibration gas. (The default value is 5.0%.)
6WHS Open the valve on the calibration gas to allow CO
2
gas to flow into the Extension.
Allow the value to stabilize before the start of the calibration. Leave the valve open
until the instrument gives a prompt that gas can be removed.
6WHS The Extension calibrates and prompts when calibration is successful.

6WHS Reopen the 5% gas valve and allow the value to stabilize.
6WHS Check that the value displayed on the Monitor is correct within the tolerance (see
Step 2 above).
6WHS Disconnect the 5% calibration gas and connect the 10% calibration gas.
6WHS Open the valve on the flow regulator to allow 10% CO
2
gas to flow into the Exten-
sion. Allow the value to stabilize.
6WHS Check that the value displayed on the Monitor is correct within the tolerance (see
Step 6 above).
If one or both values are not within tolerances, the M3015A must be exchanged.

The time counters on the sidestream CO
2
Extension must be checked before calibrating the
Instrument. As well, when parts are replaced, the appropriate counters must be reset to zero.
To check the counters, do the following:
6WHS Select the counter you want to check (either IR SourceTime or Pump OpTime.
6WHS Press and hold lightly on the TouchStrip. The counter time will display.
6WHS Release to view or press harder to reset.
As well, always observe the following guidelines:
• When calibrating the CO
2
Extension, if no parts have been replaced, check the values dis-
played on the Reset PumpOpTime and Reset IRSourceTime selections to make sure that
they are within suggested guidelines for use (15, 000 hours of continuous use). If the coun-
ter time is greater than 15, 000 hours, replace the appropriate part. See "Repairing the
Instrument".
• When calibrating the CO
2
Extension, if parts have been replaced, reset the appropriate val-
ues displayed on the Reset PumpOpTime and Reset IRSourceTime selections to zero. See
"Repairing the Instrument".
NOTE: When the PumpOpTime has been reset an INOP will be generated: “CO
2
OCCLUSION”. To clear this INOP you must perform a flow check and store the flow in
Service Mode (select “Store Flow”).
