readings. Wait a while to let the temperature of the instrument stabilize, and
then measure.

Remove the battery from the instrument, if the instrument is not in use for a
long period or is put in storage.
1-4. Environmental precautions

Do not use or store the instrument in a location where the instrument is
exposed to direct sunlight, dust, lampblack and corrosive gas, or where the
temperature and/ or humidity is high. Otherwise the measuring window gets
soiled or deteriorated, which causes inaccurate readings.

This instrument is not water-proof. Do not use in water or liquid nor make
measurements or store where it may get wet.

Keep the instrument away from an object which radiates a strong
electromagnetic wave.
1-5. Maintenance

Enclosure
Clean it with a soft cloth. To remove heavy stains, wipe it with a cloth wrung
out with diluted neural detergent.
Cautions:
Do not use chemical agents such as thinner, benzin or alcohol since these
may cause a crack or fog on the surface of the measuring window, and
consequently it may change the infrared radiation transmittance of the
plastic lens.
1-6. Relation of distance and measuring diameter
The relation between the distance and measuring diameter is as follows.
However, the ratio between distance and measuring diameter varies depending
on a distance. The more the distance increases, the larger area is needed.

2. Features
This is a contactless handheld infrared thermometer.
Temperature measurement with a K-type thermocouple is also possible.

Alarm function
The upper and lower temperature limits can be set. The red blinking
backlight indicates that the measured value is below or over the pre-set
limits.

Auto-power-off function
To save battery life, the power is shut off automatically if no key is pressed
for 6 seconds.
