OPERATION

WARNING
1) The measurement range is for thermometers only. Users should choose proper probe
types for different kinds of applications. Please make sure the target to be measured
will not exceed the temperature range of the probe to avoid permanent damage to the
thermocouple probe.
2) Caution: To avoid electric shock and thermometer damage, do not measure the live
circuit with the thermocouple probe voltage exceeding 24V AC RMS or 60V DC.
3) EMC/RFI: Readings may be affected if the unit is operated within radiofrequency
electromagnetic field strength of approximately 3 volts per meter, but the instrument's
performance will not be permanently affected.

Function Selection

1. Press Mode Key (2) for scrolling display functions as follows:
Display Function
Here will show the emissivity data. (The default emissivity is
0.95.)
Press Mode key (2), then press Up key (4) or Down key (3) to
set the emissivity, then press Mode key (2) to confirm it. The
emissivity can be changed from 0.10 (10E) to 1 (100E).
Press Mode key (2) for the Maximum (MAX), Minimum (MIN).
Differences between MAX & MIN (DIF) and Average (AVG)
modes. The special modes reading will be displayed beside
the mode icon during the measurement.
Press Up key (4) or Down key (3) to change the High Alarm
(HAL) or Lo Alarm (LAL), then press Meas. Key (6) to confirm
it. For example: When reading 26.9 °C < LAL 27 °C, the Low
icon will flash, and you will hear a beep sound.
Connect the thermocouple with the thermocouple socket (5) and
put the probe in/on the target. The Thermometer will display the
temperature automatically without pressing any button. To see
the minimum or maximum data during the probe measurement,
please hold down the Up key (4) or Down key (3).
After measuring high temp, the probe may remain HOT for
a while.
After taking the temperature, press Mode key (2) for the Memory
(M00), then press Meas. key (6) to save the measurement.
Under the Memory (M00), press the Up key (4) or Down key (3)
to display the record.
** The Thermometer will automatically shut off if left idle for more than 60sec. unless in PRB
mode. (In PRB mode, it will shut off if left idle for more than 12 minutes.)

Other Function Selection

Press Up key (4) for LOCK mode ON/OFF. The lock mode is
handy for continuous monitoring of temperatures for up to 60
In E, MAX, MIN, DIF,
minutes.
AVG mode:
Press Down key (3) for °C or °F transferred.
It shows
the reading is close to the
maximum value and
In MAX, MIN mode: Hold when close to the minimum.
the Meas. key (6) While the temperature is
between the maximum and
minimum, the bar will display
YELLOW.
A.LCD Backlight: always on.
In all modes: First, hold
the Meas. key (6)
B.Press Down key (3) for laser pointer function ON/OFF.

Temperature Measurement

1. Aim the Thermometer at the measured target with Lens (7) and press Meas. key (6) to
display the surface temperature. The Distance: Spot is 75:1. Please make sure the target
area is within the field of view.
** Data logger function (SD Card,USB): Recommend to clamp "Micro SD Card Switch" (11)
with tweezers and pull it up to enable the function. Do not push the switch too hard.

LCD Error Messages

The Thermometer incorporates visual diagnostic messages as follows:
'Hi' or 'Lo' is displayed when the temperature is measured
outside the HAL and LAL settings.
'Er2' is displayed when the Thermometer is exposed to rapid
changes in the ambient temperature. 'Er3' is displayed when
the ambient temperature exceeds the range of 0°C (32°F) ~
50°C (122°F). The Thermometer should be allowed plenty of
time (minimum 30 minutes) to stabilize to the working/room
temperature.
Error 5~9 is necessary to reset the Thermometer for all
other error messages. To reset it, turn the instrument off,
remove the battery and wait for a minimum of one minute,
reinsert the battery and turn it on. If the error message
remains, please contact the Service Department for further
assistance.
'Hi' or 'Lo' is displayed when the temperature being
measured is outside of the measurement range.
