INSTRUCTIONS
7. With the desired high temperature alarm
limit on the display, press the SET button (the
current temperature and time-of-day will appear
on the display).
Note: While in the setting mode, if no button is pressed
for ten (10) seconds, the unit automatically exits from the
setting mode.
Repeat the above steps to set the second sensor’s
alarm limits.
VIEWING THE TEMPERATURE ALARM LIMITS
1. Press the S1/S2 button to display the desired
temperature sensor.
2. Press the MODE button 3 times, the low
temperature alarm limit will appear on the
display (indicated by LO appearing on the
display).
3. Press the MODE button again, the high
temperature alarm limit will appear on the
display (indicated by HI appearing on the
display).
4. Press the MODE button a fi nal time to return
to the current temperature/time-of-day display
mode.
Note:
1. If no button is pressed for ten (10) seconds, the unit
automatically returns to the current temperature/
time-of-day display mode.
2. The time-of-day displayed when viewing the LO/HI
alarm limits is the current time-of-day and has no
relationship to when an alarm condition was achieved.
The unit does not record the time-of-day/date that the
alarm condition was initially achieved.
Repeat the above steps to view the second
sensor’s alarm limits.
ENABLE/DISABLE ALARMS
To enable the alarm to activate when a temperature
measured is outside the alarm limits, press and
release the
֠ button until “ ֠ ” appears on the
display. Each successive press of the ֠ button
will enable ( ֠ ) or disable the alarm.
When the alarm is enabled, both Sensor 1 and
Sensor 2 alarm set points will be monitored. If either
sensor reaches an alarm condition, the alarm will
sound. It is not possible to enable the alarm for one
sensor and disable the alarm for the other sensor.
ALARM SOUNDING
With the alarm enabled (
֠ ), the unit will sound
an alarm and the red LED will fl ash 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). If the alarm is sounding
based on the low alarm limit, “LO” will fl ash on the
display. If the alarm is sounding based on the high
alarm limit, “HI” will fl ash on the display.
The alarm will sound regardless of which sensor
is being displayed. Example: If Sensor 1 is being
displayed, but Sensor 2 reaches an alarm condition,
the alarm will sound and the display will automatically
change to display the Sensor 2 temperature.
The unit will continue to alarm and fl ash the
corresponding “LO” or “HI” until the temperature
being displayed is within the alarm limits. Once
the temperature being displayed is within the
alarm limits, the alarm will stop sounding and the
corresponding “LO” or “HI” will no longer fl ash;
however, the red LED will continue to fl ash to
indicate an alarm condition has occurred. To stop the
fl ashing LED, the LED must be manually stopped.
To silence an alarm manually, press any button.
When manually silenced, the corresponding “LO”
or “HI” will continue to fl ash on the display until the
temperature is within the alarm limits. The red LED
will also continue to fl ash until manually stopped.
To manually stop the fl ashing LED, once the tem-
perature has returned to a non-alarm value, press
and hold the CLEAR button for three (3) seconds.
RESET BUTTON
The RESET button, located on the back of the unit,
may be used to simultaneously reset the memory
and alarm limits for both sensors and reset the
time-of-day and date. Pressing the RESET button
has the same affect as removing the batteries from
the unit.
To reset the unit, use a pointed object to press the
RESET button. When the reset button in pressed,
the following will occur:
• The display go blank.
• The display will show all segments for
approximately 4 seconds.
• The minimum/maximum memory will be
cleared for both sensors.
• The alarm limits for both sensors will be
returned to the factory default value.
• The time-of-day and date will be cleared to
12:00:00 and 01/01/01.

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 diffi culties.
Replacing the batteries with new fresh batteries will
solve most diffi 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 in the direction of the arrow.
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 has the same affect as
pressing the RESET button. (See the “RESET
BUTTON” section.)
