are flashing on the display. The alarm settings will be saved.
Note: While in the setting mode, if no button is pressed for fifteen (15) seconds, the unit automatically
exits from the setting mode.
VIEWING THE TEMPERATURE ALARM LIMITS
1. Slide the PROBE switch to the desired position (1 or 2) to display the desired temperature sensor
readings.
2. Slide the DISPLAY switch to the ALARM position. The display will show the current temperature
and low/high alarm set points for the selected probe.
ENABLE/DISABLE ALARMS
To enable the alarm to activate when a temperature measured is outside the alarm limits, slide the
ALARM switch to the ON position.
When the alarm is enabled, both Probe 1 and Probe 2 alarm set points will be monitored. If either sensor
reaches an alarm condition, the alarm will activate. It is not possible to enable the alarm for one sensor
and disable the alarm for the other sensor.
To disable the alarm so that no alarm sounds when a temperature measured is outside the alarm limits,
slide the ALARM switch to the OFF position.
ALARM SOUNDING
With the alarm enabled, the unit will sound an alarm and the corresponding (P1/P2) red LED will flash
when a temperature being measured is outside the alarm limits that have been set (equal to or lower
than the low alarm set point, or equal to or greater than the high alarm set point). Until it has been
acknowledged/silenced (see the "Acknowledge/Silence An Alarm" section), the alarm will sound and
corresponding (P1/P2) red LED will flash continuously for the first sixty (60) seconds. After 60 seconds,
the alarm will sound and LED will flash for ten (10) seconds every minute.
If the alarm is sounding based on the low alarm limit and the probe temperature is being displayed, "LO
ALM" will also flash on the display. If the alarm is sounding based on the high alarm limit and the probe
temperature is being displayed, "HI ALM" will flash on the display.
