Field of View

The meter’s field of view is 8:1, meaning that if the meter is 8 inches from the target, the

diameter of the object under test must be at least 1 inch. Other distances are shown below

in the field of view diagram. Refer to the chart printed on the meter for more information.

Distance to Object

Measurement Notes

1. The object under test should be larger than the spot (target) size calculated by the field

of view diagram (see diagram on previous page or on side of the meter).

2. If the surface of the object under test is covered with frost, oil, grime, etc., clean before

taking measurements.

3. If an object's surface is highly reflective apply masking tape or flat black paint before

measuring.

4. The meter may not make accurate measurements through transparent surfaces such

as glass.

5. Steam, dust, smoke, etc. can obscure accurate measurements.

6. The meter compensates for deviations in ambient temperature. It can, however, take

up to 30 minutes for the meter to adjust to extremely wide ambient temperature

changes.

7. To find a hot spot, aim the meter outside the area of interest then scan across (in an up

and down motion) until the hot spot is located.

Battery Replacement

When the low battery symbol

appears on the LCD, replace the meter’s 9V battery.

The battery compartment is located on the bottom of the meter's handle. Open the

compartment by sliding the battery compartment cover off in the direction of the arrow.

Replace battery and re-install the battery compartment cover.
