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

Press Mode Key (4) for scrolling display functions as follows:
Display Function
THB (thermal bridge detection) is the default mode.
(a) IRT (infrared temperature) – Tamb (temperature
ambient) > 6.5°C:
flashing", the bar shows
beside the THB mode icon.
(b) IRT - Tamb < -6.5°C:
side flashing", the bar shows
"Lo" is beside the THB mode icon.
(c) IRT – Tamb > 5.75°C or < -5.75°C: The buzzer
and optional vibration functions will start
activating at the same time.
(d) According to the following value, "CHK" (check)
is displayed beside the THB mode icon and
please continue to observe.
4.25°C < IRT - Tamb < 6.5°C: the bar shows
≦ IRT - Tamb < 4.25°C: the bar shows
IRT - Tamb < -3.5°C: the bar shows
Here will show the emissivity data. (The default emissivity is
0.95.)
Press Mode key (4), then press Up key (2) or Down key (3) to
set the emissivity, then press Mode key (4) to confirm it. The
emissivity can be changed from 0.10 (10E) to 1 (100E).
Press Mode key (4) for the Maximum (MAX), Minimum (MIN),
Different between MAX and MIN (DIF) and Average (AVG)
modes. During the measurement, the special modes reading
will be displayed beside the mode icon.
Press Up key (2) or Down key (3) to change the High Alarm
(HAL) or Lo Alarm (LAL), then press Meas. key (6) to confirm it.
When the reading is outside the High Alarm (HAL) or Lo Alarm
(LAL) limit. The High or Low icon will flash 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.
(a) 60% < RH ≦ 75%: The screen displays
(b) 75% < RH ≦ 90%: The screen displays
(c) RH > 90%: The screen displays
Press Mode key (4) for DPT (dew point
temperature) modes. During the measurement,
the special modes reading will be displayed
beside the mode icon.
(a) IRT (infrared temperature) - DPT (dew point temperature)
> 1.9°C: The bar shows
(b) 1.1°C < IRT - DPT ≦ 1.9°C: The bar shows
displays
(c) -0.5°C < IRT - DPT ≦ 1.1°C: The bar shows
displays
(d) IRT - DPT ≦ -0.5°C: The bar shows
displays
In (b), (c) and (d) cases, the icon
for the risk of condensation as well as mold warning, the buzzer
and optional vibration functions are activated at the same time.
After taking the temperature, press Mode key (4) for the Memory
(M00), then press Meas. key (6) to save the measurement.
Under the Memory (M00), press Up key (2) or Down key (3) key
to display the record up to 50 sets. In "Memory" mode, press and
hold the "Up" key, then press the "Down" key for 2 seconds to
clear the records.
** 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.)
