LASER TARGETING
CAUTION: Eye damage may result from direct
exposure to laser light . To toggle the laser
targeting feature on or off, depress the LASER
button. The laser can be engaged from any
measurement mode.
ALL OPERATIONAL DIFFICULTIES
If this thermometer does not function properly
for any reason, please replace the battery with a
new high-quality battery (see “Battery Replace-
ment” section). Low battery power can occasion-
ally cause any number of “apparent” operational
difficulties. Replacing the battery with a new
battery will solve most difficulties.

BATTERY REPLACEMENT
Erratic readings, a faint display, no display, or
BAT appearing on the display are all indicators
that the battery must be replaced. Slide the
panel on the back of the unit in the direction
of the arrow. Unplug the old 9-volt battery and
replace with a new 9-volt alkaline battery. Slide
the battery compartment cover back into place.
Replacement battery Cat. No. 1112.
WARRANTY, SERVICE, OR
RECALIBRATION
For warranty, service, or recalibration, contact:
To decrease the temperature alarm setting
press the “C/F ▼”. Press the “ /▲” button to
increase the temperature alarm setting. Press-ing
the MODE button will lock in the alarm tem-pera-
ture value. “E”, “0.95” (pre-set emissivity) are
shown on the top left of the screen, press MODE
again and the display turns off.
When taking temperatures with power button
pressed down, an alarm will sound when the
tem-perature is above or below preset alarm
values.
EMISSIVITY ADJUSTMENT
Emissivity adjustments are used to provide a
truer temperature reading. Different materials
radiate infrared energy at slightly different tem-
peratures. The emissivity adjustment is used to
compensate for different types of materials.
The factory set emissivity of 0.95 will cover
90% of typical applications. The following in-
structions indicate how to change the emissivity
setting. The following table provides a guide of
different emissivity values for different materials.
When the emissivity of an object is Unknown
use a non-infrared thermometer, such as a
probe type thermometer to measure the object’s
surface. Then adjust the emissivity until the tem-
perature of the Infrared Thermometer matches
the temperature of the probe type thermometer.
Use this emissivity value to measure similar
materials.
To set emissivity you must pass through
the alarm setting function. Press and hold
the MODE button and the LCD displays the
alarm adjustment function. Go through the key
presses for the alarm setting function. Press
the MODE button again to display the current
emissivity value (preset to 0.95). The emis-sivity
range is 0.3 to 1.0. Press the “C/F ▼” button to
decrease and the “ /▲” button to increase the
emissivity setting. Pressing the MODE button
will lock in the value. This value will become the
unit’s default value until reset.
