14. Alarm
Displayed only if purchased as an option. The alarm menu allows the setting of various system
warnings to trigger an alarm. The number at the top of the display indicates which alarms are
enabled: A 1 indicates the associated alarm is enabled, and a 0 indicates disabled. Starting from the
left side of the screen, the alarms are in order in the following list:
1.
Lbat t – Low battery. Enables the low battery warning (absence of any battery annunciator
when running off battery) to trigger the alarm.
2.
t empu – Temperature under. Enables a low process temperature warning to trigger the alarm.
3.
t empo – Temperature over. Enables a high process temperature warning to trigger the alarm.
4.
RATEU – Rate under. Enables a low flow rate warning to trigger the alarm.
5.
r at eo – Rate over. Enables a high flow rate warning to trigger the alarm.
6.
not ot – No totalize during alarm. Inhibits the totalizer whenever there is an alarm condition.
Using this setting prevents special “out of range” flow conditions from affecting the totalizer.
Example: The temperature set points are set for the liquid state range of LN2, and the not ot
is set to ENABLED. The totalizer will not count any “gassing” of the meter (it will
not totalize when the detected temperature is outside the liquid temperature
range).
To set an alarm, press Select . A prompt to enable the Low battery alarm is
presented. Press Select again to toggle between enabLed, and dI sabLed. When
the selection is set, press Enter to accept and move to the next alarm. Continue
through all alarm settings. When the last alarm is set, the original list of all alarms is presented.
