Operating Instructions
Power
1. The meter is powered by one (1) 9V battery.
2. The transmitter base can also be powered by the 9V battery in the meter or by the
supplied AC adaptor.
IR (non-contact) Measurements
1. Hold the meter by its handle and point it toward the surface to be measured.
2. Pull and hold the trigger to turn the meter on and begin testing. The temperature
reading, the flashing ‘SCAN’ icon, the emissivity, the unit of measure and other icons
as shown in the Display Description will appear. Note: Replace the meter’s 9V battery if
the display does not switch on.
3. Release the Trigger and the reading will hold for approximately 7 seconds (HOLD will
appear on the LCD) after which the meter will automatically shut off.
4. If the Test Lock switch is set to ON (center DIP switch located inside the battery
compartment set to the right position) the meter will remain ON and continue testing
until the switch is moved to the left position (OFF) or until the battery loses power.
5. Select the temperature units (ºF/ºC) using the top switch inside the battery
compartment. The left switch position is ºC and the right position is ºF.
Backlight/Laser Pointer
1. While pulling the Trigger, push the backlight/laser button to turn on the backlight.
2. Press it again to turn on the laser pointer. When the laser is ON the laser icon will

The jack accepts a standard sub-miniature connector. Note that one plug spade is
wider than the other and the plug can only be inserted into the meter in one direction.
2. Pull the trigger to turn the instrument ON.
3. In order to keep the instrument’s power on while testing, the user can a:) hold the
trigger or b:) lock the instrument on by setting the center dip switch to the ON position
(switches are located inside of the battery compartment).
4. Repeatedly press the MODE button until the bottom display line of the LCD reads ‘T k’.
5. Hold the thermocouple in air or touch the tip of the sensor to the device that is to be
tested. The temperature shown to the right of the ‘T k’ symbol is the temperature that
the Type-K thermocouple is sensing.
6. The supplied thermocouple is rated for a maximum temperature of 482
o
F (250
o
C).
