SPECIFICATIONS
Operating Range: –4 to 122.0°F
(–20 to 50.0°C)
(Prolonged exposure to temperatures exceeding the
operating range may damage the thermometer)

1° otherwise
Accuracy: ±0.5°C between
(0 to 50°C) otherwise
±1°C
OPERATION
IMPORTANT: The intended use for this
thermometer is to monitor temperatures
inside refrigerators and freezers.
1. Press the on/off button to turn the unit on.
2. Press the °f/°c button to select the desired unit
of measure (Fahrenheit or Celsius).
3. Place the thermometer into the supplied base
and place the thermometer and base in the
desired location to be monitored.
The entire unit is completely sealed and waterproof. Do not attempt to remove the thermometer
from the bottle.
Velcro® and double sided foam
tape are supplied and may be used
to mount the thermometer or the
base side to any surface. In a refrigerator application, this prevents
the thermometer from taking up
valuable shelf space.

MINIMUM/MAXIMUM MEMORY
1. To view the minimum temperature reached
since turning on the unit, press the max/min
button. “MIN” appears on the display to indicate
the minimum temperature recorded.
2. Press the max/min button a second time, within
3 seconds, to view the maximum temperature
reached since turning on the unit. “MAX” appears on the display to indicate the maximum
temperature recorded.
Note: Three seconds after pressing the max/
min button, the unit automatically returns to the
current temperature reading. (“MIN” and/or “MAX”
are no longer displayed.)
3. Turn the unit off to clear the minimum and
maximum memories.
USING THE MEMORY TO MONITOR A
REFRIGERATOR /FREEZER
Following is an example of how to use the
memory to monitor the temperature inside a refrigerator or freezer. This example is provided only
as a helpful guide and is not intended to replace
existing facility requirements or procedures.
Unit Setup Example
1. Turn the unit on.
2. Select the desired unit of measure.
3. Place the thermometer into the supplied base.
4. Place the thermometer and base inside the
refrigerator/freezer.
At this point, allow sufcient time for the bottle
thermometer to reach equilibrium with the true
current temperature inside the refrigerator/freezer.
5. Once the thermometer has reached equilibrium, clear the minimum and maximum
temperature memory. (See the “Minimum/Maximum Memory” section.)
The memory will provide a record of the single
lowest and highest temperature achieved. When
the temperatures are recorded into the manual-
log, the memory will allow the user to see if the
temperature inside the refrigerator/freezer has
gone outside of the acceptable range.
MONITORING PROCEDURE EXAMPLE
Keep a notebook or spreadsheet as a manual log.
1. At the same time every day, record the
following into the manual log:
• Current Date and Time
• Current Temperature Reading
• Minimum Temperature Reading (MIN)
• Maximum Temperature Reading (MAX)
2. Once the above items have been manually
recorded, clear the minimum and maximum
temperature memory. (See the “Minimum/
Maximum Memory” section.)
By clearing the memory each day, the minimum
and maximum temperature memory will provide
a record of the minimum and maximum temperature that has been achieved inside the refrigerator/freezer over the past 24 hour monitoring
period. The memory will also allow the user to
see if the temperature inside the refrigerator
went outside of the acceptable range.
ALL OPERATIONAL DIFFICULTIES
If this thermometer does not function properly for
any reason, replace the battery with a new high
quality battery (see the “Battery Replacement”
section). Low battery power can occasionally
cause any number of “apparent” operational dif-
culties. Replacing the battery with a new fresh
battery will solve most difculties.
BATTERY REPLACEMENT
Erratic readings, a faint display, no display, or
appearing on the display are all indications
that the battery must be replaced. To replace the
battery, remove the three battery cover screws
located on the back of the unit. Remove the
battery cover. Replace the exhausted battery
with a new 1.5-volt, silver oxide, #357 size battery. Make certain the positive (+) side is visible.
Replace the battery cover and battery cover
screws. Do not overtighten the screws as this
may damage the unit.
NOTE: When replacing the battery cover, ensure
the screws are tightened securely to maintain
the unit’s water-proof seal.
