4.11 Powering Off the Analyzer & Purging
Power off the analyzer by pressing the
PWR
button for
at least 2 seconds, or until two beeps are heard. The
unit will count down 5 seconds before shutting down.
Pressing the
RUN/hOlD
button during this time will
stop the countdown and the analyzer will remain pow-
ered on.
If the analyzer was not purged with fresh air then the analyzer may remain
ON with its pump running and display the message “PURGING SENSORS”
as the result 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
predeterminded levels.
TIP:
Although not recommended, the purging process can be bypassed
by pressing the
PWR
button a second time.
4.12 Low Battery Alarm
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 operating time that remains depends on many
factors (e.g., pump and backlight powered on or off and the type and condi-
tion of the batteries).
