due to age or vibration.
This may lead to data loss.
Condensation may occur if the unit is moved from
one environment to another where the difference in
temperature is great.
Use the unit in an environment where the ambient
temperature is from -10 to 60℃ and the humidity is
90％RH (no condensation) or less.
To prevent damage to the unit from static
electricity, remove static electricity from your body
by touching metal around you (door knob, window
frame) before touching the unit.
Static electricity may cause not only damage to the
unit, but may cause breaks in or a loss of data.
If the unit will not be used for period of time, for
safety reasons please remove the battery.

Cautions about using the Sensors
Cautions about using the temperature sensor TR-0106
The possible temperature measurement range for
this sensor is -40 to 110℃. Please use it within this
range.
It is possible to use just one extension cable per
temperature sensor.
Cautions about using
the temperature/humidity sensor TR-3100
The sensor can measure temperature within the
range of 0 to 50℃ and humidity within the range
of 10 to 95％RH. Only use the sensor within these
ranges.
If extremely severe temperature changes occur, the
humidity measurements may appear abnormal.
Once the sensor's temperature becomes stable, the
measurements will return to normal.
This sensor is not waterproof. Do not get wet.
The temperature/humidity sensor cable cannot be
extended.
When measuring with the temperature/humidity
sensor in an environment of 0 to 50℃ and less
than 30％RH, the measurements may sometimes
fluctuate. This is not abnormal.
Cautions about using the Sensors
[Handling the temperature/humidity sensor]
- The temperature/humidity sensor should probably be changed after a
period of about one year. After removing the sensor from its package,
please change the temperature/humidity sensor after one year’s usage.
During use the temperature/humidity sensor will accumulate impurities (dirt)
on the surface of the sensor causing the sensor's accuracy and sensitivity
to decrease. If the sensor is being used in a bad environment (smoky or
dusty places) it may be necessary to change the sensor sooner.
- When the temperature/humidity sensor is not being used, please place it in
the attached vinyl bag with the drying agent included and store it in a cool
dark place with a temperature of between 5 to 25℃ and a humidity of below
30％RH.
- Attached to the temperature/humidity sensor are two stickers: a wetness
detection sticker and a temperature detection sticker. If either of the stickers
shows abnormality, you should change the old sensor to a new one
immediately.
Wetness Detection
Sticker
Temperature Detection
Sticker
- Wetness Detection Sticker
Informs you that the sensor has been wet.
Normal:
Under normal conditions, black
dots will appear on a white
background.
Abnormal:
Under abnormal conditions, it
will turn to red.
- Temperature Detection Sticker
Informs you that the sensor measured a temperature measurement over 60℃.
60 Normal:
Under normal conditions, the
number
「60」 will lightly appear on a
pinkish white background.
60 Abnormal:
Under abnormal conditions, the
number
「60」 will clearly appear on a
red background.
