OPERATION
Press and continue to hold down the
MEAS button to take temperature
readings. The unit will take temperature
readings while the MEAS button is
pressed and held.
The thermometer has a 1:1 distance
spot/ratio and should be held as close
to the target as possible for the most
accurate measurement. (See the
Distance Spot/Ratio section for details.)
After the MEAS button is released,
the last temperature measured will
be displayed for approximately 15
seconds, the display will then turn off
automatically.
SELECTING UNITS OF MEASURE
1. Locate the hole to the °F/°C button
on the back of the unit (there is a
corresponding hole in the pocket
clip).
2. Press and release the MEAS button
to turn on the display.
3. With a pointed object (such as a
paperclip), depress the °C/°F
button. Each press will toggle the
display between °C and °F.
DISTANCE SPOT/RATIO
There are other factors that may
affect measurement accuracy. The
target must completely ll the spot
diameter seen by the infrared sensor;
otherwise readings will be inuenced
by the surface surrounding the
target. The ratio of the distance to
the size of the spot being measured
is 1:1. For example, an object’s
diameter of 100mm can be measured
from 100mm. For an accurate
measurement, the unit should be held
as close to the target as possible.
ALL OPERATIONAL DIFFICULTIES
If this thermometer does not func-
tion properly for any reason, replace
the batteries with new high quality
batteries (see Battery Replacement
section). Low battery power can occa-
sionally cause any number of “appar-
ent” operational difculties. Replacing
the batteries with new fresh batteries
will solve most difculties.
