Low Battery Alarm Empty Battery Icon
When the batteries are nearly depleted, an empty battery icon appears in the upper-right corner of the display, and a short beep is sounded every 10 seconds.
After a low battery alarm occurs, the analyzer will continue to operate for only a few minutes.
The amount of operating time that remains de- pends on many factors (e.g., pump and backlight being ON or OFF, and the type and condition of
the batteries).

Operation

4.10 Turning OFF the Analyzer & Purging

Turn OFF the analyzer by pressing the I/O but- ton for at least 2 seconds, or until two beeps are heard. The unit will count down 5 seconds before shutting down, giving the operator an opportu- nity to keep the analyzer turned ON by pressing the RUN/HOLD button.

If the PCA 2 was not purged with fresh air as described in Section 4.8, then the analyzer may remain ON with its pump running and display the message “PURGING SENSORS” as the re- sult of combustion gases still being present inside the analyzer. At this time the operator should ensure that the probe is removed from the stack, allowing the analyzer to purge itself with fresh air. The 5-second-shutdown sequence will not begin until the gas levels inside the analyzer drop below predetermined levels:
