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 and 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.
4. To exit from the alarm event display mode, press and
release the EVENT DATE TIME button, or simply do
not press any button for  fteen (15) seconds.
DISPLAY MESSAGES
LL.LL appearing on the display indicates that the
temperature being measured is outside of the
temperature range of the unit, or that the probe is
disconnected or damaged.
BENCH STAND
The unit is supplied with a bench stand that is a part
of the back of the unit. To use the bench stand, locate
the small opening at the bottom back of the unit. Place

To close the stand, simply snap it shut.
ALL OPERATIONAL DIFFICULTIES
If this unit does not function properly for any reason,
replace the batteries with new high-quality batteries
(see the “Battery Replacement” section). Low battery
power can occasionally cause any number of “apparent”
operational dif culties. Replacing the batteries with new
fresh batteries will solve most dif culties.
BATTERY REPLACEMENT
Erratic readings, a faint display, no display, or a
battery symbol appearing on the display are all
indications that the batteries must be replaced.
Remove the battery cover, located on the back of the
unit, by sliding it down. Remove the exhausted batteries
and replace them with two (2) new AAA alkaline batteries.
Make certain to insert the new batteries with the proper
polarity as indicated by the illustration in the battery
compartment. Replace the battery cover.
Replacing the batteries will clear the minimum/maximum
memories, the high/low alarm settings, and the time-of-
day/date.
