built-in laser pointer increases target accuracy while the backlight
LCD and handy push-buttons combine for convenient, ergonomic
operation. Type K thermocouple functionality is also built-in. Proper
use and care of this meter will provide years of reliable service.

4. 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

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.

Accuracy: Given at 18 to 28°C (64 to 82°F), less than 80%RH.
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.

•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
“ “ 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 “ “ button also allows you to
access the High
•Alarm(HAL), Low Alarm(LAL),Emissivity(EMS) and
data logger(LOG).Each time you press
•MODE, you advance through the mode cycle.
•Pressing the “ “ button also allows you to
access the Type kTemp. Measurement.

•Select the temperature units (°C or °F) by using the switch.
•To lock the unit on for continuous measurement, slide the middle
switch right. If the trigger is pulled while the unit
is locked on, the laser and backlight will be turned 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 “ “
button on the keypad.
•To activate the alarms, please slide the botto switch
right.
•To set values for the High Alarm (HAL), Low Alarm (LAL) and Emissivity
(EMS), firstly active the display by pulling the trigger or pressing the
“ “ button, then press the “ “ button until the appropriate
code appears in the lower left corner of the display, press the “ “
and “ “ buttons to adjust the desired values.

10.Measurment Operation
Hold the meter by its and point it toward the surface
to be measured.
Pull and hold the 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 in the upper left
corner of the LCD.
Release the Trigger and the HOLD icon will appear on the LCD
indicating that the reading is being held.
The meter will automatically power off after approximately 7 seconds
after the trigger is released.(Unless the unit is locked on)

•In the EMS mode, press and hold the Laser/Backlight button until
the “ ” icon on the left side of LCD blinking. At this time, “ = --”
will appear at the upper side of the LCD; IR temperature value will
be in the middle of LCD; and Type K temperature value is at the lower
side of the LCD.
•Contact the Type K probe to the object surface and test the temperature
of same point with IR measurement. After both values are stable,
press “ “ or “ “ button for confirmation. Then emissivity of
the object will be shown at the upper side of the LCD.
•Press “ “ button or trigger to enter normal measurement.
•When the IR value is not corresponding to the TK value, or IR and
TK tested the different points, no emissivity will be obtainable or a
wrong emissivity will be obtained.
•The temperature of the target should be higher than the environment
temperature. Normally, 100°C is suitable for obtaining a higher accuracy
emissivity. After obtaining the emissivity, if the difference between
IR value (in the middle of LCD) and TK value (at the lower side of
LCD) is too big, the obtained emissivity will be incorrect. It’s necessary
to obtain a new emissivity.
