IMPORTANT SAFETY INFORMATION
Read and understand all of the instructions and safety infor-
mation in these operating instructions before using this meter.
Use the meter only as specified in this manual; otherwise, the
protection provided by the meter may be impaired.
A WARNING statement identifies hazardous conditions
and actions that could cause bodily harm or death.

Operating the Thermometer
To measure temperature, aim the thermometer at an object and
pull the trigger key. Be sure to consider the distance to spot size
ratio. The laser is used for aiming only.

Optical Resolution
Ratio of the distance from the measured object vs. the spot size
of the measurement area.
Emissivity
Emissivity is the ratio of infrared energy emitted from an
object versus the infrared energy emitted by a black body.
The emissivity of the perfect black body is 1. All other
materials have an emissivity ratio between 0.1 (highly
reflective) to 1.0 (Ideal black). Emissivity is determined
primarily by the material from which an object is con-
structed and its surface finish.
The thermometer allows emissivity adjustment for the
type of surface being measured. Refer to the following
emissivity table.

Automatic Power Off
The thermometer will automatically shut off if left idle for more
than 60 seconds unless it is in the PRB mode. If in the PRB
mode, the unit will automatically shut off if left idle for more than
12 minutes.
STORAGE
The thermometer should be stored at room temperature between
- 4 to 149°F (- 20 to 65°C).
LENS CLEANING
The lens should be kept clean at all times. Care should be
taken when cleaning the lens using only a soft cloth or cotton
swab with water. Allow the lens to fully dry before using the
thermometer.
Note: DO NOT submerge the unit in water.
LCD ERROR MESSAGES
The thermometer incorporates visual diagnostic messages as
follows: ‘Hi’ or ’Lo’ is displayed when the temperature being
measured is outside of the settings of HAL and LAL. ‘Er2’ is
displayed when the thermometer is exposed to rapid changes
in the ambient temperature. ‘Er3’ is displayed when the ambi-
ent temperature exceeds 32°F (0°C) or 122°F (+50°C). The
thermometer should be allowed to stabilize to the working/
room temperature (minimum 30 minutes). Error 5~9, for all
other error messages it is necessary to reset the thermometer. To
reset it, turn the instrument off, remove the battery and wait for
a minimum of one minute, reinsert the battery and turn on. If the
error message remains please contact the Service Department
for further assistance.
BATTERIES
The thermometer incorporates visual low battery warning as
follows:
Batteries OK Batteries Low Batteries Dead
measurements battery needs to be measurements are
are possible replaced, measurements not possible
are still possible
When the ‘Low Battery’ icon indicates the batteries are
low, the batteries should be replaced immediately with two AAA,
1.5Vbatteries.Pleasenote:Itisimportanttoturntheinstrument
