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

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.

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.

using the

F 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.

7.MEASURMENT OPERATION

Hold the meter by its Handle Grip and point it toward the surface

to be measured.

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.

While measuring, the SCAN display icon will appear ins the upper

left hand corner of the LCD.

Release the Trigger and the HOLD display icon will appear on the

LCD indicating that the reading is being held.

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.

8.BATTERY REPLACEMENT

As battery power is not sufficient, LCD will display “ ”

replacement with one new battery type 9V is required.

Open 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.

Reminders

Not recommended for use in measuring shiny or polished metal

surfaces ( stainless steel, aluminum, etc.).See Emissivity

The unit cannot measure through transparent surfaces such as

glass. It will measure the surface temperature of the glass instead.

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.
