IR Measurements

1. Point the meter toward the surface to be measured

2. Press and hold the MEASURE button. The meter will turn ON,

“SCAN” will blink and the measured temperature will be displayed.

3. Release the MEASURE button and the last reading will be held

(HOLD will appear) in the display for approximately 6 second and

then the meter will turn off.

4. In the measure mode, press the LASER button to turn the laser

pointer on or off.

Measurement considerations:

 The thermometer must be acclimated to ambient temperature for

accurate measurements. Allow approximately 30 minutes

acclimation time when the storage area and use area have a large

temperature differential.

 If known, adjust the emissivity value to match the emissivity of the

surface being measured. If unknown, use 0.95.

 The surface measured should be cleaned of frost, dust or other

materials before accurate measurements can be made.

 Recommended measuring distance is 2” to 36” (5cm to 91cm)

 Apply black tape or paint to highly reflective surfaces to increase the

emissivity and improve the accuracy of the measurement.

 The object being measured should be larger than the spot size as

illustrated in the distance to spot diagram.

Battery Replacement

The battery icon appears when the batteries need replacing. Open the

battery compartment on the rear of the meter, replace the batteries and
