Thermometer
Operating Instructions
The thermometer is a non-contact infrared
HACCP thermometer that also includes a
thermocouple probe. You can select only one
measurement Mode at a time, but you can change
the Mode at will. Please remember to keep away
from baby and children and don’t use it for
medically- related applications.
* Special Features:
1. Food Code Zone Display;
2. Water Proof (IP65)
In Non-contact Infrared Thermometer function (IRT Mode)
# The white light wills automatically turns ON while the Scan button is pressed.
Simply aim the thermometer at the measure target with “Infrared Lens” and press Scan (infrared) key to display the
surface temperature. The distance to target ratio is 2.5:1 therefore the thermometer should be positioned as close to
the target as possible.
Distance:Spot (FOV)= 2.5:1
Emissivity = 0.1~1 Step.01
Wave Length = 8-14um
While scanning, the newest temperature will be updated on the LCD and the measurement will continue as long as
the Scan (infrared) key is depressed. When the Scan (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.

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 Scan (infrared) key button is pressed.
To utilize the lock mode, please press Scan (infrared) key

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 Scan (infrared) key

In Contact Thermocouple Probe function (COT Mode)
Attach the thermometer at the measure target with “Probe” and press Probe key to continuously display the
temperature for up to 4 minutes. After that the device will automatically shut off to extend the battery life.
Press Probe key will interrupt the scanning to display the last temperature with a 'Hold' wording.
To reenter scanning just press Probe key again.
1. Do not twist the probe and rotate the probe in wrong direction.
2. Over stress on probe may cause break.
3. After measure high temp, the probe may remain HOT for a while.
4. Probe is dangerous for human when the probe is in an open position. Remember to hold the probe
back when not in use.
The probe of contact thermometer may be damaged if
exceeding the specification of
measurement temperature range.
To avoid electric shock and thermometer damage, do not measure live circuit where voltage
exceeding 24V AC RMS or 60V DC
with the thermocouple probe.
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
o
C(40
o
F) or appears with icon ” ” indicates a safe
holding temperature above 60
o
C(140
o
F).
When temperature is between 4
o
C and 60
o
C, the red LED with icon ”
” will appear and indicate that the temperature is fallen within the HACCP
“Danger Zone” from 4
o
C to 60

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
range of the instrument, ‘Hi’ when higher than +250
o
C (482
o
F) and ‘Lo’ when
lower than -55
o
C (-67
o
F).
「
」
「
」
「

「
」
‘Er2’ is displayed when the thermometer is exposed to rapid changes in the
ambient temperature. ‘Er3’ is displayed when the ambient temperature exceeds 0
o
C
(32
o
F) or +50
o
C (122
o
F). The thermometer should be allowed plenty of time
(minimum 30 minutes) to stabilize to the working/room temperature.

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.

BATTERIES
STORAGE & CLEANING
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 it, do not submerge any part of the thermometer. The thermometer should be stored at room
temperature between –20 to +65
o
C (-4 to 149
o
F).
