all opeRational DifficUltieS
If this thermometer does not function properly for
any reason, replace the batteries with new high
quality batteries (see Battery Replacement section).
Low battery power can occasionally cause any
number of “apparent” operational difculties.
Replacing the batteries with new fresh batteries will
solve most difculties.

BatteRY ReplaceMent
Erratic readings, faint readings, no display, or
appearing on the display are all indications that
the batteries must be replaced.
To replace the batteries:
1. Remove the rubber plug from the battery cover.
2. Remove the battery cover screw.
3. Remove the battery cover.
4. Remove the exhausted batteries and replace
them with two (2) new AAA alkaline batteries.
Make certain to install the new batteries in the
directions indicated in the battery compartment.
5. Replace the battery cover.
6. Replace the battery cover screw and tighten
securely.
7. Replace the rubber plug. This plug is required in
order to achieve a water resistant seal.

Infrared temperature is displayed at the top of the
display. Press and continue to hold down the SCAN
button to take temperature measurements. The unit
will take temperature measurements and update the
display while the SCAN button is pressed and held.
While the SCAN button is held, the white spotlight
will illuminate the general area being measured.
After the SCAN button is released, the last
temperature measured will be displayed for
approximately 15 seconds, the display will then
turn off automatically. HOLD will appear on
the display when the SCAN button has been
released to indicate that the unit is no longer taking
temperature measurements.

Probe temperature is displayed at the bottom
portion of the display. Rotate the temperature
probe to the desired position. Place the probe
in contact with the material to be measured then
press and release the PROBE button to take
temperature measurements. When the PROBE
button is pressed and released, the unit will take
temperature measurements continuously for 4
minutes, and will automatically shut off.
To manually turn the unit off while displaying the
probe temperature, press and hold the PROBE
button for 2 seconds, HOLD will appear on the
display and the last temperature measured will
be displayed for approximately 15 seconds, the
display will then turn off automatically.
Selecting °f oR °c
To change the display mode from °F to °C or from
°C to °F, press and release the SCAN button,
press the MODE button four (4) times, then press
and release the SCAN button.
Haccp cHecK featURe
Hazard Analysis and Critical Control Points (HACCP)
is a systematic preventive approach to food safety
and pharmaceutical safety that addresses physical,
chemical, and biological hazards as a means of
prevention rather than nished product inspection.
HACCP is used in the food industry to identify
potential food safety hazards, so that key actions,
known as Critical Control Points (CCPs) can be
taken to reduce or eliminate the risk of the hazards
being realized.
The HACCP check feature incorporated into this
thermometer are the following critical temperature
zones:
Safe Cool/Frozen condition - Indicated by
a green light when the temperature measured is
below 40°F/4°C.
Safe Holding condition - Indicated by a green
light when the temperature measured is above
140°F/60°C.
Danger Zone condition - Indicated by a red
light when the temperature measured is between
40 to 140°F/4 to 60°C. This is the temperature
range in which microorganisms (such as bacteria)
live and grow.
MiniMUM teMpeRatURe DiSplaY MoDe
This mode is only available for infrared temperature measurement.
In MIN mode, the lowest temperature measurement
taken while pressing the SCAN button is displayed.
This value will update each time a new lower
temperature is measured.
To enter MIN mode, press and release the SCAN
button, press the MODE button (MIN will appear on
the display), then press and hold the SCAN button
to take temperature measurements.
After the SCAN button is released, the last
minimum temperature measured will be displayed
for approximately 15 seconds, the display will
then turn off automatically. HOLD will appear
on the display when the SCAN button has been
released to indicate that the unit is no longer taking
temperature measurements.
MaXiMUM teMpeRatURe DiSplaY MoDe
This mode is only available for infrared temperature measurement.
In MAX mode, the highest temperature measurement
taken while pressing the SCAN button is displayed.
This value will update each time a new higher
temperature is measured.
To enter MAX mode, press and release the SCAN
button, press the MODE button twice (MAX will
appear on the display), then press and hold the
SCAN button to take temperature measurements.
After the SCAN button is released, the last
maximum temperature measured will be displayed
for approximately 15 seconds, the display will
then turn off automatically. HOLD will appear
on the display when the SCAN button has been
released to indicate that the unit is no longer taking
temperature measurements.
locK fUnction
This mode is only available for infrared temperature measurement.
The lock function allows the thermometer to take
measurements without having to press and hold the
SCAN button. When the lock function is activated,
the unit will take continuous infrared temperature
measurements for 60 minutes and will then turn off
automatically to preserve battery life.
To activate the lock mode, press and release the
SCAN button, press the MODE button three (3)
times, then press and release the SCAN button.
LOCK will appear on the display and the °F/°C
indicator will ash to indicate that the unit is in the
lock mode and is taking measurements.
To manually de-activate the lock mode, press and
hold the SCAN button for 2 seconds. LOCK will no
longer appear on the display to indicate that the unit
is no longer using the lock function.
After the SCAN button is released, the last
temperature measured will be displayed for
approximately 15 seconds, the display will then
turn off automatically.
DiStance Spot/Ratio
There are other factors that may affect infrared
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 2.5:1. For
example, an object’s diameter of 100mm can be
measured from 250mm.
eMiSSiVitY
Emissivity adjustment is optional. Emissivity
adjustments are used to provide a truer temperature
reading. Different materials radiate infrared energy
at slightly different temperatures. The emissivity
adjustment is used to compensate for different
types of materials. The default emissivity of 0.95
will cover 90% of typical applications.
The emissivity table provides a guide of different
approximate emissivity values for different materials.
When the emissivity of an object is unknown, use
a non-infrared thermometer, such as a thermometer
with a surface probe to measure the object’s
surface temperature. Adjust the emissivity until
the temperature of the Infrared Thermometer
matches the temperature of the surface probe.
The emissivity value arrived at by this method
may be used to measure similar materials.
To adjust the emissivity (optional):
1. Press and release the SCAN button, press the
MODE button ve (5) times. The emissivity
value (# #E) will appear on the display.
2. To adjust the emissivity value, press the SCAN
button. Press and hold to advance the display
rapidly.
The emissivity can be set from 0.10 to 1.00 in 0.01
increments.
Note: The emissivity value is expressed by a factor of
100, meaning that an emissivity value of 0.95 will appear
as 95E on the display. More examples: Emissivity
value of 1.00 will appear as 100E, emissivity value of
0.15 will appear as 15E on the display, etc.
3. Once the desired emissivity value appears on the
display, press the MODE button to conrm the
value. (HOLD will appear on the display and the
unit will turn off after 15 seconds.)
This emissivity value will be used for all temperature
measurements until the value is re-set.
