ZyTemp TCT303F Operating Instructions

In Non-contact Infrared Thermometer function (IRT Mode)
# The white light will automatically turns on while the Scan button is pressed.
Distance:Spot (FOV)= 2.5:1 Simply aim the thermometer at the measure target with "Infrared Lens"
and press Scan (infrared) key to display the surface temperature. The
Emissivity = 0.1~1 Step.01
distance to target ratio is 2.5:1 therefore the thermometer should be
Wave Length = 8um-14um
positioned as close to the target as possible.
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.
Mode Selection MIN MAX LOCK
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 Scan (infrared) key
pressing Scan (infrared) key for measurement.
To utilize the maximum mode, please press Scan (infrared) key
pressing Scan (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 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

The thermometer is a non-contact infrared
thermometer, also with Probe thermometer. You
can select only one Mode at the same time but
can change the Mode at will. Please remember to
keep away from baby and children and don't use it
for safety related applications.

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 "

holding temperature above 60
When temperature is between 4
" will appear and indicate that the temperature is fallen within the
HACCP "Danger Zone" from 4

」 0 C (32 F) or +50 C (122 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.
