of a person or an animal

Inspect for damage or for

any shortage of parts or
accessories before use

Replace the batteries immediately after the

battery indicator flashes o Do not use the
thermometer near explosive gases, steam,
or dust

Note that an object with high reflectivity will normally cause the measured

temperature value to read much lower than the actual temperature

Use the device only as described in this User Guide

Cautions

To avoid thermometer damage, please avoid the following hazards:

EMF from welding

induction heaters o Static
electricity

Thermal shock caused by large or abrupt environmental temperature

changes; wait 30 minutes to allow the thermometer to stabilize to new
environmental conditions

Do not use this device in excessively high temperature environments

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 254mm

The spot sizes indicate 90% encircled energy.

Operation

NOTES:

1. In HOLD MODE, Use the MODE Button to change MAX/MIN/DIF/AVG.

2.In Measurement Mode, if the TYPE-K thermocouple is connected, the
Type-K data will displays in the lower left quarter automatically,during
this this time, it cannot display EMS.

3.To set values for the High Alarm (HAL), Low Alarm (LAL) and Emissivity
(EMS), press and hold the MODE Button until the appropriate code appears in
the display, press the Up and Down Buttons to adjust the desired values.

4-You can turn ON/OFF the Backlight/Laser by pressing Laser/Backlight
Button at any state.

MODE Button Function

Press the MODE Button also allows you to access the set state,

Emissivity (EMS), °C/°F, HAL adjustment, LOW adjustment, Each time
you press set you advance through the mode cycle.

The diagram shows the sequence of functions in the mode cycle.

EMS Adjustment

The Emissivity (EMS) digitally adjustable from 0.10 to 1.0.

The High (Low) alarm adjustable form -50 to 1000°C (-58 to 1832°F)

TRIG

The function of TRIG means that when the TRIG is turn on ,press and hold

the trigger for more than 10 minutes ,the device will turn off.

MAX MIN DIF AVG Display

MAX MIN DIF AVG indicate the MAX MIN DIF AVG record that displays
between the pressing and

MAX=Maximum; Maximum value of
measurement. MIN=Minimum; Minimum
value of measurement. DIF=Difference;
Difference value of measurement.
AVG=Average; Average value of
measurement.

Measurement 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.

The meter will automatically power down after approximately 8
seconds after the trigger is released.

**NOTES:

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.

Battery Replacement

If the battery power is not sufficient, LCD will display Replace with

a new 9V battery.

Open the battery cover, then take out the battery from instrument and

replace with new battery and place the battery cover back.

**Notes

How it Works

Infrared thermometers measure the surface temperature of an object.

which is collected and focused onto a detector.

reading, which is display on the unit.

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

Field of View

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.

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

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.

Maintenance

Repairs or service are not covered in this manual and should only be

carried out by qualified trained technician.

Periodically, wipe the body with a dry cloth.
Do not use abrasives or solvents on this instrument.
