measurement operation

① Hold the meter by the handle and point it to the surface to be measured.

②Pull and hold the trigger to turn on the meter and start the test. If the battery is OK, the display will light up. If the display does not light up, replace the batteries.

③Release the trigger, and the HOLD display icon will appear on the LCD, indicating that the reading is in progress. In the HOLD state, press the UP button to turn on or off the laser. Then press the down button to turn the backlight on or off.

④The meter will automatically shut down about 7 seconds after the trigger is released. (unless instrument is locked)

NOTE: Measurement Considerations

Hold the handle of the meter, point the infrared sensor to the object whose temperature is to be measured, and the meter will automatically compensate for the temperature deviation from the ambient temperature . Keep in mind that it takes up to 30 minutes to adjust for wide ambient temperatures, followed by high temperature measurements, and some time after low temperature measurements (and a few minutes).
