The thermometer is a non-contact infrared thermometer. Simply aim the thermometer at the target and press the ‘Scan
key’ to display the surface temperature.
Laser Information: (for models with
Laser only)
By pressing the ‘Scan key’, the device
will begin to measure the temperature
of the target and the laser will operate.
CAUTION!
1. WHEN DEVICE IS IN USE, DO NOT
LOOK DIRECTLY INTO THE LASER
BEAM–PERMANENT EYE DAMAGE
MAY RESULT.
2. USE EXTREME CAUTION WHEN
OPERATING THE LASER.
3. NEVER POINT THE DEVICE
TOWARDS ANYONE’S EYES.

Always with the real time Max data
1.Power on: Press the “Scan. key”.
2.Temperature taking: When it’s power on, press the “Scan. key”, will get the
real time Max data immediately and the reading of measurement will be continuous updated.
HACCP CHECK
The “HACCP CHECK” feature is incorporated in our thermometer
temperature to graphically indicate critical temperature zone. The icons and
LED indicators located above the display indicate a food product stays in a
safe or unsafe HACCP “ Danger Zone” temperature. The green and red
LED light will always be lit before power off.
A Green LED appears with icon ” ” indicates a safe cool or frozen
condition below 4oC(40oF) or appears with icon ” ” indicates a safe
holding temperature above 60oC(140oF).
When temperature is between 4oC and 60oC, the red LED with icon ” ”
will appear and indicate that the temperature is fallen within the HACCP “Danger Zone” from 4oC to 60oC (40~140oF).
°C OR °F MODE
To change the thermometer from ‘°C’ to ‘°F’ or from ‘°F’ to ‘°C’, firstly turn the instrument on by pressing the ‘Scan key’,
then press the ‘Mode key’ one time, the ‘°C’ or ‘°F’ symbol will flash, press the ‘Scan key’ to change to scale.
EMISSIVITY RANGE
The infrared thermometer is supplied with a default emissivity of 0.95. The emissivity of the thermometer can be
changed from 0.05 (5E) to 1 (100E). Changes should only be carried out by experienced personnel. To change the
emissivity, firstly turn the instrument on by pressing the ‘Scan’ button, then press the ‘Mode’ button two times for
emissivity function. The 95E will flash on the LCD screen, then press the ‘Meas.’ button to adjust the emissivity value,
press the ‘Mode’ button again to exit the set up screen. For information relating to the emissivity of specific materials,
please contact the nearest retailer. Note: non-contact infrared thermometers are not recommended for use in measuring
the temperature of shiny or polished metals.
BAR DISPLAY: The fixed setting range for bar display is 20~220°C and Center=120°C.
The bar display will be updated comply with the measurement reading
changed.
LCD ERROR MESSAGES
The thermometer incorporates visual diagnostic messages as follows:
「」
「」
‘Hi’ or ’Lo’ is displayed when the temperature being measured is outside of the measurement
range.
「」
「 」
‘Er2’ is displayed when the thermometer is exposed to rapid changes in the ambient temperature.
‘Er3’ is displayed when the ambient temperature of the thermometer EXCEEDS 0°C (32°F) OR
+50°C (122°F). In both cases you should allow plenty of time (minimum 30 minutes) for the
thermometer to stabilize to the working/room temperature.
「 」
For all other error messages it is necessary to reset the thermometer. To reset the thermometer,
