How to use
Please have the unit adapt to the measurement environment for at least
30 minutes before using.
1. Displaying the Current Temperature
 When the external probe is not connected, the temperature around the
unit is displayed.
 When the external connected is connected, the unit automatically
displays the temperature reading detected by the external sensor.
2. Displaying the MAX/MIN Temperature
The MAX & MIN temperature readings are displayed all the time.
The MAX/MIN memory starts by following situations.
 Load or replace the battery
 Press the RESET key (Previous MAX/MIN memory will be deleted.)
Note: The MAX/MIN memory is kept even if the external probe is removed
or connected. To clear the previous data, press the RESET key.
(1) Use of internal sensor
The main unit can be used in a refrigerator that its inside temperature
is -5˚C or higher. Do not use the main unit in lower than -5˚C state.
Secure the protective cap into the sensor jack at that time.
(2) Use of external probe
By using the external probe, it is possible to check
the inside temperature of a refrigerator from
outside.
Put the external probe inside through the gap of the
refrigerator door hinge as shown in the picture.
Note: The probe cord is delicately made. Carefully
handle it not to break the wire.
