INTRODUCTION
Thank you for purchase of the IR Thermometer. This Series is capable
of non-contact (infrared) temperature measurements at the touch of a
button. The built-in laser pointer increases target accuracy while the
backlight LCD and handy push-buttons combine for convenient,
ergonomic operation.
The Non-contact Infrared Thermometers can be used to measure the
temperature of objects’ surface that is improper to be measured by
traditional (contact) thermometer (such as moving object, the surface
with electricity current or the objects which are uneasy to be touched.)
Proper use and care of this meter will provide years of reliable service.
FEATURES:
Precise non-contact measurements
High distance to target ratio measures smaller surface areas at
greater distances
Widest temperature range
Unique flat surface, modern housing design
Built-in laser pointer
Automatic Data Hold
@/Ｒswitch
Emissivity digitally adjustable from 0.10 to 1.0
MAX,MIN,DIF, AVG temperature displays
Backlight LCD display
Built-in laser pointer
Automatic selection range and Display Resolution 0.1皢C(0.1皢F)
Trigger lock

WIDE RANGE APPLICATION:
Food preparation, Safety and Fire inspectors, Plastic molding, Asphalt,
Marine and Screen printing, measure ink and Dryer temperature,
HVAC/R, Diesel and Fleet maintenance.
1. SAFETY
Use extreme caution when the laser beam is turned on.
Do not let the beam enter your eye, another person’s eye or the
eye of an animal.
Be careful no to let the beam on a reflective surface strike your
eye.
Do not allow the laser light beam impinge on any gas which can
explode.

2 Distance & Spot Size
As the distance (D) from the object increases, the spot size (S) of the
area measured by the unit becomes larger. The relationship between
distance and spot size for each unit is listed below. The focal point for
each unit is 914mm (36”). The spot sizes indicate 90% encircled energy.

MODE Button Function
The infrared thermometer measures
Maximum (MAX), Minimum (MIN),
Differential (DIF), and Average (AVG)
Temp. Each time you take a reading.
This data is stored and can be
recalled with the MODE button until a
new measurement is taken.
When the trigger is pulled again, the
unit will begin measuring in the last
mode selected.
Pressing the MODE button also
allows you to access the High
Alarm(HAL),Low Alarm(LAL),
Emissivity(EMS).Each time you press
MODE ,you advance through the
mode cycle.
The diagram shows
the sequence of functions in
the MODE cycle.

laser and backlight will turn on if they have been activated. When the unit
is locked on, the backlight and laser will remain on unless it is turned off
using the Laser/Backlight button on the keypad.
To activate the alarms, please slide the bottom switch SET ALARM right.
To set values for the High Alarm (HAL), Low Alarm (LAL) and Emissivity
(EMS), firstly active the display by pulling the trigger or press the MODE
button, then press the MODE button until the appropriate code appears
in the lower left corner of the display, press the UP and DOWN buttons to
adjust the desired values.

7.MEASURMENT OPERATION
p"Hold the meter by its Handle Grip and point it toward the surface
to be measured.
q"Pull and hold the Trigger to turn the meter on and begin testing.
The display will light if the battery is good. Replace the battery if
the display does not light.
r"While measuring, the SCAN display icon will appear ins the upper
left hand corner of the LCD.
sRelease the Trigger and the HOLD display icon will appear on the
LCD indicating that the reading is being held.
tThe meter will automatically power down after approximately 7
seconds after the trigger is released.(Unless the unit is locked on)
Note: Measurement considerations
Holding the meter by its handle, point the IR Sensor toward the object
whose temperature is to be measured. The meter automatically
compensates for temperature deviations from ambient temperature.
Keep in mind that it will take up to 30 minutes to adjust to wide
ambient temperatures are to be measured followed by high
temperature measurements, some time (several minutes) is required
after the low (and before the high) temperature measurements are
made.This is a result of the cooling process, which must take place for the IR
sensor.

8.BATTERY REPLACEMENT
pAs battery power is not sufficient, LCD will display “ ”
replacement with one new battery type 9V is required.
qOpen battery cover, then take out the battery from instrument and
replace with a new 9-Volt battery and place the battery cover back.

9. NOTES:
How it Works
Infrared thermometers measure the surface temperature of an object.
The unit’s optics sense emitted, reflected, and transmitted energy,
which is collected and focused onto a detector. The unit’s electronics
translate the information into a temperature reading, which is display n
the unit. In units with a laser, the laser is used for aiming purposes
only.
Field of View
Make sure that the target is larger than the unit’s spot size. The
smaller the target, the closer you should be to it. When accuracy is
critical, make sure the target is at least twice as large as the spot size.
Distance & Spot Size
As the distance (D) from the object increases, the spot size (S) of the
area measured by the unit becomes larger. See: Fig: 1.
Locating a hot Spot
To find a hot spot aim the thermometer outside the area of interest,
then scan across with an up and down motion until you locate hot
spot.

13
Reminders
p"Not recommended for use in measuring shiny or polished metal
surfaces ( stainless steel, aluminum, etc.).See Emissivity
q"The unit cannot measure through transparent surfaces such as
glass. It will measure the surface temperature of the glass instead.
r"Steam, dust, smoke, etc., Can prevent accurate measurement by
obstructing the unit’s optics.
Emissivity
Emissivity is a term used to describe the energy-emitting
characteristics of materials.
Most (90% of typical applications) organic materials and painted or
oxidized surfaces have an emissivity of 0.95 (pre-set in the unit).
Inaccurate readings will result from measuring shiny or polished metal
surfaces. To compensate, cove the surface to be measured with
masking tape or flat black paint. Allow time for the tape to reach the
same temperature as the material underneath it. Measure the
temperature of the tape or painted surface.
