2. To adjust the temperature alarm set point, press the ▲or ▼ button. (Do
not press the trigger while adjusting the alarm set points). Press and hold
to advance the display rapidly.
To turn the Hi/Low Alarm function On/Off:
1. Locate the SET ALARM ON/OFF switch in the handle.
2. Slide the switch to the desired position.
With the Alarm function set to ON, (indicated by ((( HI and LOW ))) appearing
on the display), while taking temperature measurements, an alarm will sound
when the temperature measured is above or below the High and Low alarm
set points that have been entered. If the temperature is above the High
Alarm set point, ((( HI will flash on the display. If the temperature is below the
Low Alarm set point, LOW ))) will flash on the display.
The alarm will sound regardless of the Display Mode if the temperature
measured is above or below the High and Low alarm set points that have
been entered.
LOCK FUNCTIONS
The lock function allows the thermometer to take long-term measurements
without having to hold the trigger. When the lock function is activated, the
unit will take continuous temperature measurements until the LOCK function
is set to OFF.
To use the lock function:
1. Locate the LOCK ON/OFF switch in the handle.
2. Slide the switch to the ON position.
3. Close the handle.
4. Press and release the trigger to begin taking measurements.
The unit will continue to take measurements without holding the trigger until
the LOCK ON/OFF switch is set to OFF.
5. When finished taking measurements, locate the LOCK ON/OFF switch in
the handle.

6. Slide the switch to the OFF position.
7. Close the handle.
EMISSIVITY
Emissivity adjustment is optional. Emissivity adjustments are used to provide
a truer temperature reading. The emissivity value appears at the top of the
display (ε=#.##).
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 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 the MODE button until EMS appears on the display.
2. To adjust the emissivity value, press the or button. (Do not press the
trigger while adjusting the emissivity value). Press and hold to advance
the display rapidly.
The emissivity can be set from 0.10 to 1.00. This emissivity value will be
used for all temperature measurements until the value is reset.
DISPLAY MESSAGES
“1” will appear on the display when the temperature being measured is
outside the range of the unit.
ALL OPERATIONAL DIFFICULTIES
If this thermometer does not function properly for any reason, replace the
battery with a new high-quality battery (see Battery Replacement section).
Low battery power can occasionally cause any number of “apparent”
operational difficulties. Replacing the battery with a new fresh battery will
solve most difficulties.
BATTERY REPLACEMENT
Erratic readings, faint readings, no display, or a battery symbol appearing on
the display are all indications that the battery must be replaced.
Locate the indentions on either side of the plastic
case near the trigger. Open the battery compartment
by pulling the rubber portion of the handle out and
away from the trigger. Pull hard, it requires a good
amount of force to open the battery compartment.
Remove the exhausted battery and replace it with a
new 9-volt alkaline battery. Close the battery cover
by snapping it shut.
