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.

5. MEASURMENT OPERATION
A. POWER ON/OFF
The meter automatically powers when the key is pressed. Pull the ON/HOLD trigger key to take a reading. Read the
measured temperature on the LCD. (Fig. A) The meter powers OFF automatically approximately 7 seconds after the
ON/HOLD trigger key is released.

B. SELECTING UNITS(℃/℉)
Select temperature units (degrees or ) by first pressing the ON/HOLD key and then pressing the or key. The
units will be seen on the LCD. (Fig. B)
Presses the or key again to switch the unit (scale) again. See Fig. C.
Fig.B Fig.C
C. DATA HOLD
This meter automatically holds the last temperature reading on the LCD for seven seconds after the ON/HOLD key is
released. No extra key presses are necessary to freeze the displayed reading. (Fig. D)

D. BACKLITE LCD
Select backlight by first pressing the ON/HOLD key and then pressing the Backlight key. Repeat the procedure to turn
the backlight OFF. (Fig.E)

E. LASER POINTER
To turn the laser pointer ON, press the LASER key while pressing the ON/HOLD key. (Fig. F) Press the LASER key
again to turn the laser OFF. (Fig. G)

F. 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.
6. BATTERY REPLACEMENT
1. As battery power is not sufficient, LCD will display “BAT” 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. (Fig.H)

7. Notes:
zHow 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 display on the unit is. In units with a laser, the
laser is used for aiming purposes only.
zField 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.
zDistance & 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.
zLocating 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.
zReminders
1.Not recommended for use in measuring shiny or polished metal surfaces ( stainless steel, aluminium,
etc.).See Emissivity
2.The unit cannot measure through transparent surfaces such as glass. It will measure the surface
temperature of the glass instead.
3.Steam, dust, smoke, etc., can prevent accurate measurement by obstructing the unit’s optics.
zEmissivity
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.

NOTE: "This instrument doesn’t have ATEX protection, so it should not be used in potentially explosive
atmospheres (powder, flammable gases)."
