Do not let the beam enter your eye, another person’s eye or the eye of an animal!
This may cause severe eye injuries.
• In lock mode, press the up button or down
button to adjust the Emissivity. HAL (LOW)
on/off. Press the up button or down button
to turn on or turn off. Press the Measurement
Trigger to confirm the High (Low) alarm mode.
Hal (LOW) adjustment. The high (Low) alarm
adjustable form -50 to 550 °C (-58°F ~ 1022°F)
Switching C/F
• Select the temperature
units (°C or °F) using the
°C/°F switch
1
.
• Max indicate the max record that
displays between the pressing and
releasing the “ON/OFF” button
each time.
MEASUREMENT OPERATION
• Hold the Thermometer by its Handle Grip and
point it toward the surface to be measured.
• Pull and hold the Trigger to turn the Thermom-
eter on and begin testing. The display will light
if the battery is good. Replace the battery if
the display does not light.
• Release the Trigger and the HOLD display
icon will appear on the LCD indicating that the
reading is being held. In HOLD status, press
the UP button to turn on or off the laser. And
press the DOWN button to turn on or off the
backlight.
• The Thermometer will automatically power
down after approximately 7 seconds after the
trigger is released.(Unless the unit is locked
on).
Note:
Measurement considerations
Holding the Thermometer by its handle,
point the IR Sensor toward the object
whose temperature is to be measured.
-
The Thermometer automatically compensates
for temperature deviations from ambient
temperature. Keep in mind that it will take the
Thermometer up to 30 minutes after high tem-
perature measurement to adjust to the ambi-
ent temperatures, 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.
5. BATTERY REPLACEMENT
• As battery power is not sufficient, LCD will
display “.......”and replacement with one new
battery type 9V is required.
• Open battery cover, then take out the battery
out of the battery compartment and replace
with a new 9-Volt battery and place the battery
cover back.
6. How it Works
• Infrared thermometers measure the surface
temperature of an object. The unit’s optics
sensor does emit, reflect and transmit en-
ergy, which is collected and focused onto a
detector. The unit’s electronics translate the
information into a temperature reading, which
is displayed on 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.
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.
