the object with the IR probe, adjust the
“Emissivity Adjust VR” (Fig.1-10) with a small
flat head screwdriver until the readings
match.
•
Turning the VR to the left (counter-
clockwise) will adjust the emissivity to
0.10 to 0.94.
• Turn the VR all the way to the right to
reset the probe to 0.95.
FACTORS AFFECTING
MEASUREMENT
1. Measurement Field/Distance:
• The ideal distance between the probe
and the surface being measured is
10 mm (3/8 inch)
• The size of the object should be at
least 2.5 mm (3/32 inch)
2. Positioning: For the most accurate
reading, the probe should be held as
perpendicular to the object as possible.

MEASUREMENT PROCEDURE
1. Plug the IR probe plug (Fig.1-9) into the
meter input socket (Fig.1-13).
2. Turn meter on using the POWER switch
(Fig.1-6).
3. Choose scale using the °C/°F button
(Fig.1-3). The chosen scale will appear
in the lower right of the display.
4. Select the resolution by moving the
1°/0.1° switch (Fig.1-7). Use “1°” for
general use.
5. While holding the IR probe main body
(Fig.1-11), point the tip of the probe
(Fig.1-12) at the object being measured.
The meter will display the surface
temperature.
• The ideal distance between the probe
and the surface being measured is
10 mm (3/8 inch)
• The size of the object should be at
least 2.5 mm (3/32 inch)
