1. Hold the thermometer by its handle, and point it toward the
surface to be measured.
2. Pull and hold the trigger for at least 1 sec to turn on the
thermometer and make measurement, reading will be displayed
on the main display.
Note: Each time you pull the trigger, the pull must last at least 1
sec.
3. During measurement, the symbol " SCAN " will flash on the
display, and when you release the trigger, the measurement stops
and the symbol " HOLD " appears indicating that the last reading
is locked.
4. The thermometer will turn off automatically if you have not
operated the thermometer for about 30 secs.
Note:
1. Make sure that the target surface is larger than the thermometer's
spot size. The smaller the target surface, the closer you should be
to it ( see the " FIELD OF VIEW " section ).
When accuracy is critical, make sure the target is at least twice as
large as the spot size.
2. To find a hot or cold spot, aim the thermometer outside the
desired area. Then, slowly scan across the area with an up
and down motion until you locate the hot or cold spot. ( see the
figure on the next page )
