5. OPERATION
WARNING
The measurement range is for thermometers only. Users should choose proper probe
types for dierent 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.
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.
EMC/RFI: Readings may be aected if the unit is operated within radiofrequency
electromagnetic eld strength of approximately 3 volts per meter, but the instrument's
performance will not be permanently aected.
5.1 Function Selection
Press Mode Key (4) for scrolling display functions as follows:
Display Function
THB (thermal bridge detection) is the default mode.
Here will show the emissivity data. (The default emissivity is
0.95.)
Press Mode key (4) for the Maximum (MAX), Minimum (MIN),
Dierent between MAX and MIN (DIF) and Average (AVG)
modes. During the measurement, the special modes reading
will be displayed beside the mode icon.
** The Thermometer will automatically shut o if left idle for more than 60sec., unless in PRB
mode. (In PRB mode, it will shut o if left idle for more than 12 minutes.)

Press Mode key (4), then press Up key (2) or Down key (3) to
set the emissivity, then press Mode key (4) to conrm it. The
emissivity can be changed from 0.10 (10E) to 1 (100E).
Press Up key (2) or Down key (3) to change the High Alarm
(HAL) or Lo Alarm (LAL), then press Meas. key (6) to conrm it.
When the reading is outside the High Alarm (HAL) or Lo Alarm
(LAL) limit. The High or Low icon will ash and you will hear a
beep sound.
Connect the thermocouple with Thermocouple Socket (10) 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 (2 or Down key (3).
After measure high temp, the probe may remain HOT for a
while.
Press Mode key (4) for the RH% (relative
humidity) mode, then press Up key (2) for DBT
(dry bulb temp), WBT (wet bulb temp.) modes.
During the measurement, the special modes
reading will be displayed beside the mode
icon.

5.3 Temperature Measurement
Simply aim the thermometer at the measure target with Lens (7) and press Meas. key (6) to
display the surface temperature. The Distance:Spot is 30:1. Please make sure the target area
is within the eld of view.
5.4 LCD Error Messages
The Thermometer incorporates visual diagnostic messages as follows:
‘Hi’ or ’Low’ is displayed when the temperature being
measured is outside of the settings of HAL and LAL.
‘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, for all other error messages it is necessary to
reset the thermometer. To reset it, turn the instrument o,
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.
‘Hi’ or ’Lo’ is displayed when the temperature being
measured is outside of the measurement range.
6. MAINTENANCE
CAUTION
BEFORE ATTEMPTING BATTERY REMOVAL OR REPLACEMENT, DISCONNECT
EXTERNAL PROBES FROM AN ARTICLE UNDER TEST.
6.1 Fitting and replacing the battery
The Thermometer incorporates visual low battery indication as follows:
‘Battery OK’: measurements are possible
‘Battery Low’: battery needs to be replaced, measurements are still
possible
‘Battery Exhausted’: measurements are not possible
When the ‘Low Battery’ icon indicates the battery is low, the battery should be replaced
immediately with AAA, 1.5V batteries. Please note: It is essential to turn the instrument o
before replacing the battery; otherwise, the Thermometer may malfunction.
Dispose of used battery promptly and keep away from children.
If the device is not used for a long time, turn the power o, remove and store the batteries in
a cool, dry place.
