Operating Instructions
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, and the unit of measure will appear.
Note: Replace the 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. The only
exception to this is if the TEST LOCK switch is set to ON.
Note: Select the temperature units (ºF/ºC) using the top switch inside the battery
compartment
Backlight/Laser Pointer
1. While pulling the Trigger, push the backlight/laser button once to turn on the
backlight.
2. Press it again to turn on the laser pointer. When the laser is ON the laser icon will
appear in the LCD.
3. Press the laser button to turn the backlight off.
4. Pressing it again turns the laser off.
Note: Backlight and Laser settings will be retained after the meter powers down.
Type-K (contact) Measurements
1. Plug the Type-K thermocouple sensor into the jacks at the bottom of the instrument.
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’.
The temperature shown to the right of the ‘T k’ symbol is the temperature that the
Type-K thermocouple is sensing.
5. Hold the thermocouple in air or touch the tip of the sensor to the device that is to be
tested. The LCD’s bottom temperature display will provide the measurement value.
6. The supplied thermocouple is rated for 482
o
F (250
o
C).
