TRACEABLE
THERMOMETER
INSTRUCTIONS
ON/OFF BUTTON
The ON/OFF button located on the back of the
unit may be used to turn the unit off when the
thermometer is not being used. The minimum/
maximum memory and alarm limits are not cleared
when the unit is turned off. To turn the unit off,
press the ON/OFF button. Each successive press
of the ON/OFF button will turn the unit on or off.
No alarms will sound and no minimum/maximum
memory will be recorded when the unit is off.
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 openings on either side of
the bottom of the unit. Place your fi ngernail into
one of the openings and fl ip the stand out. To
close the stand, simply snap it shut.
WALL MOUNTING THE UNIT
Set a screw into the wall at the desired location. Do
not set the screw fl ush to the wall, the head of the
screw will need to slip into the receptacle on the
back of the unit. Once the screw has been properly
set, hang the unit in place by sliding the receptacle
on the back of the unit over the head of the screw.
USING THE ALARM AND MEMORY TO
MONITOR A REFRIGERATOR/FREEZER
Following is an example of how to use the alarm
and 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.
In this example, the refrigerator temperature must
be monitored and logged for each 24 hour period
and certain actions must be taken if temperature
falls below 0°C or rises above 5°C at any time
during the 24 hour period.
Unit Setup Example
1. Plug the probe into the unit.
2. Install the battery.
3. Place the probe sensor inside the refrigerator.
4. Place the display outside the refrigerator.
5. Select the Probe Temperature Display mode.
(See the “Temperature Display Modes” section.)
At this point, if using a bottle probe, allow suffi cient
time for the bottle probe to reach equilibrium with
the true current temperature inside the refrigerator.
6. Set the probe temperature low alarm limit to 0°C.
(See the “Setting Probe (OUT) Temperature Alarm
Limits” section.)
7. Set the probe temperature high alarm limit
to 5°C.
(See the “Setting Probe (OUT) Temperature Alarm
Limits” section.)
8. Enable the alarms.
(See the “Enable/Disable Alarms” section.)
9. Clear the minimum and maximum memory.
(See the “Clearing the Probe (OUT) Temperature
Memory” section.)
10. Select the probe temperature with Min/Max
memory display mode.
(See the “Temperature Display Modes” section.)
The alarm limits have been set and the alarm has
been enabled. The display has been set to show
the current temperature inside the refrigerator along
with the minimum and maximum temperature that
has been achieved inside the refrigerator.
If the temperature inside the refrigerator goes
outside the alarm limits (equal to or lower than the
low alarm set point, or equal to or greater than the
high alarm set point), the alarm will sound.
If no one is available to hear the alarm sounding
(overnight), and the temperature returns to an in-
range condition, 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 that the temperature inside the refrigerator
had 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 both the minimum and
maximum temperature memory.
(See the “Clearing the Probe (OUT) Temperature
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 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
when there was no one available to hear the alarm
(overnight).

ALL OPERATIONAL DIFFICULTIES
If this unit 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 diffi culties.
Replacing the battery with a new fresh battery 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 battery must be replaced.
Open the battery compartment by depressing the
tab located at the top of the battery cover and
lifting it out. The battery cover is hinged at the
bottom so that the battery compartment may be
opened without completely removing the battery
cover. Remove the exhausted battery and replace
with a AAA alkaline battery. Make certain to insert
the new battery with the proper polarity as indicated
in the illustration in the battery compartment.
Close the battery cover.
Replacing the battery has the same affect as
pressing the RESET button. (See the “RESET
BUTTON” section.)
