The alarm will sound and corresponding LED will flash regardless of which sensor is being displayed
and regardless of the display mode. Example: If Probe 1 is being displayed and the DISPLAY switch is
set to MIN MAX, but Probe 2 reaches an alarm condition, the alarm will sound and the P2 LED will
flash.
The unit will continue to alarm and flash the corresponding (P1/P2) red LED until the alarm has been
acknowledged/silenced by either pressing the SILENCE ALM button or by sliding the ALARM switch to
the OFF position (see the "Acknowledge/Silence An Alarm" section). The unit will continue to alarm and
flash the corresponding (P1/P2) red LED even if the temperature being measured returns to an
in-range/non-alarm condition.
ACKNOWLEDGE/SILENCE AN ALARM
While alarming, the alarm may be acknowledged/silenced in one of the following ways:
1. Slide the ALARM switch to the OFF position. Setting the ALARM switch to the OFF position will
silence the alarm, but when it is switched back to the ON position, if the temperature being
measured is still in an alarm condition, the alarm will sound. Setting the ALARM switch to the OFF
position prevents any/all alarms from sounding.
2. Press the SILENCE ALM button. Pressing the SILENCE ALM button will silence the alarm, the
alarm will not sound again until the temperature being measured has returned to an in-range
condition and then goes to an alarm condition.
VIEWING ALARM EVENT VALUE DATE & TIME
When the thermometer achieves an alarm condition, the date and time for the most recent alarm
condition is stored into memory. The most recent alarm event achieved is stored for each probe (P1/P2)
independently. To view the most recent alarm event:
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 the low/high alarm set value.
3. Press the EVENT DATE TIME button, the most recent alarm set value that was achieved along with
the time-of-day/date the alarm occurred will appear on the display.
Note: The value that appears at the top of the display while displaying the event date/time, is the alarm
set value that caused the alarm condition, not the actual temperature achieved while in the alarm
condition. If nothing appears on the display when the EVENT DATE TIME button is pressed, this
indicates that either the unit has not achieved an alarm condition, or that the alarm set values have
been changed for the selected probe since the unit last achieved an alarm condition.
