4. Preparations Before Taking Measurements
4.1. How to Install the Batteries
Make sure to turn the power off when replacing batteries.
Note: To maintain the waterproofing performance, firmly tighten the screws on
the battery cover.
4.2. How to Use the Hand Strap
Place the enclosed hand strap on your wrist to prevent the instrument from
dropping.
Loop the thin cord of the strap through the hole and then pull the other end of
the hand strap through that loop.
(1) Remove both
screws and
open the cover
of the battery
housing.
(2) Pay attention
to the
orientation of
the batteries.
(3) Install the
batteries.
(4) Reattach the battery
housing cover, tighten
both screws, and then
press the edge of the
cover to secure it.

4.3. How to Set the Sensor
Set the sensor to the main unit as shown in the illustration below. It is designed
so that if the sensor orientation is incorrect, it cannot be fully inserted. If the
sensor is forcefully inserted, failure may result. Please check the sensor’s
orientation before inserting it.

8. Error Messages
8.1. Indication of a Broken Wire of the Sensor
If the sensor has a broken wire or is disconnected, the
burnout (broken wire) indication is displayed.
If this indication is displayed, replace the sensor with a
new one or connect the sensor.
8.2. Overrange Indication
When the temperature in measurement exceeds the
measurable range, the overrange indication is
displayed.
If the wire of the sensor is about to become broken,
this overrange indication may be shown. If it is clear
that the temperature in measurement is within the
measurable range, check the sensor.
Even if the overrange indication is shown, it will not
damage the instrument. However, the sensor may be
consumed, so relocate it to a place where the
temperature is at a heat-resistant temperature or a
lower temperature.
8.3. Battery Voltage Drop Indication
When batteries are depleted and the battery
indication on the screen becomes , replace the
batteries with new ones.

- In direct sunlight
- Subject to heavy vibrations
- High humidity (85%RH or more)
- High temperature atmosphere (50°C or higher)
- Filled with dust, waste, corrosive gas, and/or salt
- High electromagnetic field
To store the instrument for a long time, it is recommended to remove the
batteries and store the unit in the original packaging at time of delivery.
9.2. When the Case of the Instrument Gets Dirty

10. Troubleshooting: Before Contacting Support
If you find any abnormalities or become unable to operate the instrument, first
check for the following items. If you still cannot solve the issue, please contact
your retailer or our company.
(1) The instrument does not operate when power is turned on:
- Is the orientation of the batteries in the correct manner?
Reset the batteries.
- Have the batteries been depleted?
Install new batteries.
(2) The indicated values of temperature are unstable:
- Is the wire of the sensor almost broken or is the sensor deformed?
Do an appearance check of the sensor.
- Is the sensor connector inserted fully?
Re-insert the connector.
- Is the sensor sufficiently making contact with the object of measurements?
Change how to set the sensor.
- Is the measurement environment in a high electromagnetic field (such as a
large motor)?
- Relocate the instrument or use the shield.
(3) If measurement errors are too large:
- Are the thermocouple types of the sensor and the instrument the same?
Replace the sensor.
- Is the head of the sensor deformed?
Replace it with a new one.
(4) Keys are not responding:
- Is there any burn out (broken wire) indication shown?
Set the sensor.
- Are any functions running?
Terminate various functions and retry to operate the keys.
