Operation

CAUTION:

Do not place a hot probe inside the instrument’s carrying case.
Allow the probe to cool before storage.

2. Loosen the thumbscrew on the probe stop; then remove the probe and

probe stop from the stack.

3. If data was saved during the combustion test, you can turn off the

analyzer and review or print the stored data at a later time as de-
scribed in Sections 4.10 and 4.23.

4.3.5 Turning Off the Analyzer and

Purging the CO Sensor

Turn off the analyzer by pressing the

key.

If the

key is pressed while the CO reading is 100 ppm or higher, the

pump will automatically turn on (if not already running) to purge the
analyzer of CO.

IMPORTANT! The analyzer’s probe must be removed from
the stack during the purging process to allow fresh air to be
drawn through the analyzer.

The following message is displayed while the analyzer is being purged.

PURGING CO SENSOR

As soon as the CO level falls below 100 ppm, the pump turns off and the
analyzer starts its normal 5 second turn-off sequence.

To abort the purging process and immediately start the analyzer’s turn-off
sequence, press the

key.

NOTE: Turning the analyzer off initiates a 5-second delay,
during which time the unit can be turned on again without
any warmup time. You can turn the analyzer back on during
this 5-second delay by pressing the

key.
