INTRODUCTION

Thank you for purchase of the IR Thermometer. This 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:

z Precise non-contact measurements
z High distance to target ratio measures smaller surface areas at greater distances
z Widest temperature range
z Unique flat surface, modern housing design
z Built-in laser pointer
z Automatic Data Hold
z ℃/℉ switch
z Emissivity Digitally adjustable from 0.10 to 1.0
z MAX,MIN,DIF, AVG temperature displays
z Backlight LCD display
z Built-in laser pointer
z Automatic selection range and Display Resolution 0.1ºC(0.1ºF)
z Trigger lock
z Set high and low alarms

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

z Use extreme caution when the laser beam is turned on.
z Do not let the beam enter your eye, another person’s eye or the eye of an animal.
z Be careful no to let the beam on a reflective surface strike your eye.
z Do not allow the laser light beam impinge on any gas which can explode.

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.

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.

(for cycling through the mode loop)

③ Down button (for EMS,HAL,LAL)

④ Laser/Backlight on/off button

(pull trigger and press button to

MOD E

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

MODE 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.

Switching C/F ,LOCK ON/OFF and SET ALARM.

① C/F
② LOCK ON/OFF
③ SET ALARM

Select the temperature units (oC or oF) using the oC/oF switch

To lock the unit on for continuous measurement, slide the
middle switch LOCK ON/OFF right. If the trigger is pulled
while the unit is lock on, the 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.

6. MEASURMENT OPERATION

① Hold the meter by its Handle Grip and point it toward the surface to be measured.
② 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.

③ While measuring, the SCAN display icon will appear ins the upper left hand corner of the LCD.

④ Rele ase the Trigger and the HOLD display icon will appear on the LCD indicating that the

reading is being held.

⑤ The 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.

7. BATTERY REPLACEMENT

① As battery power is not sufficient, LCD
will display “ ” replacement with one
new battery type 9V is required.

② Open battery cover, then take out the

battery from instrument and replace with a
new 9-Volt battery and place the battery
cover back.

8. NOTES:

z 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 on the unit. In units
with a laser, the laser is used for aiming purposes only.

z 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.

z 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.

z 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.

z Reminders

① Not recommended for use in measuring shiny or polished metal surfaces ( stainless steel,

aluminum, etc.).See Emissivity

② The unit cannot measure through transparent surfaces such as glass. It will measure the surfac e

temperature of the glass instead.
③Steam, dust, smoke, etc., Can prevent accurate measurement by obstructing the unit’s optics.
z 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.
