In Non-contact Infrared Thermometer function (IRT Mode)
#The laser will automatically turns on while the Scan button is pressed.
For all other error messages it is necessary to reset the thermometer. To reset it, waiting for auto
power off, remove the battery and wait for a minimum of one minute, reinsert the battery and turn
on. If the error message remains please contact the Service Department for further assistance.
While scanning, the newest temperature will be updated on the LCD and the measurement will continue as long as
the Meas.(infrared) key is depressed. When the Meas.(infrared) key is released, icon “Hold” will appear on the display
and the last measurement will remain visible for 15 seconds before the display goes blank.
WHEN DEVICE IS IN USE, DO NOT LOOK DIRECTLY INTO THE LASER BEAM–PERMANENT EYE
MAY RESULT.
USE EXTREME CAUTION WHEN OPERATING THE LASER.
NEVER POINT THE DEVICE TOWARDS ANYONE’S EYES.

MINIMUM OR MAXIMUM MODE
The thermometer will display the minimum or maximum reading during the measurement period only until the Mode
key is pressed.
To utilize the minimum mode, please press Meas.(infrared) key Mode key Meas.(infrared) key. And keep
pressing Meas.(infrared) key for measurement.
To utilize the maximum mode, please press Meas.(infrared) key Mode key *twiceMeas.(infrared) key. And keep
pressing Meas.(infrared) key for measurement.
LOCK MODE
The lock mode is particularly useful for continuous monitoring of temperatures. The thermometer will continuously
display the temperature for up to 60 minutes or until the Meas.(infrared) key button is pressed.
To utilize the lock mode, please press Meas.(infrared) key Mode key *three timesMeas.(infrared) key.
oCOR oFMODE
To change the ‘oC’ or ‘oF’ mode, please press Meas.(infrared) key Mode key *four timesMeas.(infrared) key.
Same steps can be taken when switching from oF to oC.
EMISSIVITY
The infrared thermometer is supplied with a default emissivity of 0.95. The emissivity can be changed from 0.10 (10E)
to 1 (100E). Changes should only be carried out by experienced personnel. 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.
To change the emissivity, please Meas.(infrared) key Mode key *five timesMeas.(infrared) key for each 0.01
(1E) adjustmentMode key.
STORAGE &CLEANING
It should be stored at room temperature. The sensor lens is the most delicate part of the thermometer. The lens
should be kept clean at all times, care should be taken when cleaning the lens using only a soft cloth or cotton swab
with water or medical alcohol, allowing the lens to fully dry before using the thermometer. Do not submerge any part
of the thermometer.
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.
Emissivity = 0.1~1 Step.01
Distance:Spot (FOV)= 12:1 Simply aim the thermometer at the measure target with “Infrared Lens” and
press Meas.(infrared) key to display the surface temperature. The distance
Wave Length = 8um-14um to target ratio is 12:1.Please make sure the target size is within the field of
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 4
oC(40oF) or appears with icon ””indicates a safe
holding temperature above 60
oC(140oF).
When temperature is between 4
oC and 60oC, the red LED with icon ”
”will appear and indicate that the temperature is fallen within the HACCP “Danger Zone” from 4oC to 60o
o
‘Er2’ is displayed when the thermometer is exposed to rapid changes in the
ambient temperature. ‘Er3’ is displayed when the ambient temperature exceeds
「」「 」
0oC (32oF) or +50 oC (122 o
F). The thermometer should be allowed plenty of time
(minimum 30 minutes) to stabilize to the working/room temperature.
FI50 Thermometer Operating Instructions
The thermometer is a non-contact infrared thermometer. Please remember to keep away from baby
and children and don’t use it for safety related applications.
