Traceable Thermometer/Alarm
Some units are equipped with a Traceable Thermometer/ Alarm that simultaneously displays
minimum, maximum, and current interior temperatures and provides a visual and audible signal
when the temperature inside the unit falls outside the set temperature range.
The temperature sensor, or probe, is enclosed in a glycol-filled bottle that you insert into the location
to be monitored, such as inside a refrigerator or freezer, once the unit has been programmed. The
thermometer/alarm itself can be attached to the door of the unit with the magnet on the back, or it
can be placed on a convenient table or shelf.
Power to the thermometer/alarm is supplied with a lithium iron disulfide battery with a 10-year shelf
life. When it is inserted correctly, the unit will beep and all segments of the LCD display will be
temporarily activated. (Note that alarm temperatures will have to be reset after replacing the battery.)
The temperature display can be switched between Celsius (°C) and Fahrenheit (°F) by sliding the
°C/°F button located on the back of the unit.
Function of Controls
•
MODE/RESET Key:
Press ONCE to reset Max/Min temperature record. When the unit is
sounding an alarm, press ONCE to turn off the beeping sound.
•

the High-Alarm or Low-Alarm will still flash until the temperature goes back to normal or the
Alarm function is turned off.
Programming the Alarms
The thermometer displays the internal temperature of the unit being monitored, as well as the
maximum and minimum temperatures reached. The maximum and minimum readings reflect the
highest and lowest temperatures since the battery was inserted or since the MODE/RESET key was
last pressed. If the temperature rises above or falls below the set temperature range, the alarm will
sound. By default, the high alarm temperature setting is 8°C (46.4°F) and the low alarm temperature
setting is 2°C (35.6°F). To reset these limits, follow these instructions:
•
High Alarm Temperature Setting:
Press the HIGH/LOW key ONCE, then press MODE/RESET
to enter the High Alarm temperature setting mode. Use the Up and Down arrows to adjust the
temperature accordingly. Press MODE/RESET once again to confirm the setting.
•
Low Alarm Temperature Setting:
Press the HIGH/LOW key TWICE, then press MODE/RESET
to enter the Low Alarm temperature setting mode. Use the Up and Down arrows to adjust the
temperature accordingly. Press MODE/RESET ONCE to confirm the setting.
• By default, the low and high alarms should be audible. To turn alarms on/off:
•
Audible High Alarm Setting:
To make sure the high alarm is audible, press HIGH/LOW key
ONCE (to activate HI-SET on the screen). Then press the ALERT ON/OFF key ONCE to
activate the HIGH-ALARM beeping sound. Press again to deactivate.
•
Audible Low Alarm Setting:
To make sure that the low temperature alarm is audible, press the
HIGH/LOW key TWICE to activate LOW-SET on the screen. Then press the ALERT ON/OFF
key ONCE to activate the LOW-ALARM beeping sound. Press again to deactivate.
NOTE:
For an activated high alarm and low alarm buzzer, the display should indicate HI-ALARM
and LO-ALARM as shown here.
