OPERATION

Press and continue to hold down the
trigger to take temperature readings.
The unit will take temperature readings
while the trigger is pressed and held
(SCAN appearing on the display indicates
measurements are being taken).
After the trigger is released, the last
temperature measured will be displayed
for approximately 15 seconds and the
display will turn off automatically. HOLD
will appear on the display when the
trigger has been released to indicate that
the unit is no longer taking temperature
measurements.

DISTANCE SPOT/RATIO

There are other factors that may affect
measurement accuracy. The target
must completely fill the spot diameter
seen by the infrared sensor; otherwise
readings will be influenced by the
surface surrounding the target. The ratio
of the distance to the size of the spot
being measured is 11:1. For example,
an object's diameter of 100mm can be
measured from 1100mm.

Laser targeting is always active when

the trigger is pressed and held, the laser
beam will be emitted.

direct exposure to laser light.

MAXIMUM TEMPERATURE

While taking measurements, the unit
will automatically record the maximum
temperature reading that has been
measured. This value will appear on the
display to the right of MAX.
