Usage and Part Names
Battery
(1) Installing
Batteries
Loose the screw at the lower part of the
battery cover, pressing the battery
compartment cover as shown and removing
it. Install batteries positioning the negative
and positive poles properly as shown inside
the compartment. Then fasten the screw
and put the cover back.
Note:
If the battery cover is not screwed in tightly, the waterproof property will be
deteriorated, and performance may be deteriorated due to water penetration in
the unit.
However, do not fasten the screw too tightly when replacing the battery cover.
(2) Replacing
Batteries
Residual quantity of the batteries is displayed on the low battery symbol in the
display. When the low battery symbol becomes
, the batteries have run
out. Replace the batteries with new batteries.
Note:
When replacing batteries, replace both batteries at the same time.
Battery Cover
Measurement Display
Aim the measuring window at the measuring target, and press the
MEASURE key. Holding down the MEASURE key, confirm if the
laser beam irradiates the measuring position properly. Adjust the
position, if the laser beam does not irradiate the measuring position
properly. Measuring continues while the MEASURE key is being
held down. When the MEASURE key is released, the measured
value is held for about 30 seconds, and then the power is shut off
with the Auto Power Off function.
If the measuring window is aimed at a new target and the
MEASURE key is pressed while the measured value is being held,
the temperature of the new target will be measured. When the
MEASURE key is released, the newly measured temperature will be
held.
Settings
Normally only the object emissivity is selectable. The emissivity is set at
0.95 at the factory. The emissivity is displayed during measurement
(except for emissivity 0.95. When nothing appears on the display, it
means that the emissivity is 0.95.) Five variations of emissivity ranging
from 0.8 to 1.0 can be set at every 0.05 step.
The emissivity can be altered by setting the 3 digits (2nd, 3rd and 4th
digits from left) of the 4-digit slide switch in the lower part of the battery
compartment. The setting mode of the slide switch is displayed below the
battery part. Remove the batteries, and set as required according to the
displayed setting mode.
If necessary, the measurement unit can be switched to Fahrenheit ( )
(with the leftmost digit of the 4-digit slide switch.)

Setting Emissivity (Reference)
Quantity of infrared radiation emitted from objects depends on variables
such as the objects’ material, surface conditions and measuring
temperatures. The table below shows emissivity of some objects.
Please note that these values are just for reference. Please also refer to
the estimated emissivity using the separately sold black body tape.

Estimated Emissivity Using the Black Body
Tape
If a measuring object accepts sticking of adhesive tapes, stick a piece of the black
body tape (emissivity: 0.94) to the object, and measure the temperature after setting
the emissivity to 0.95.
