4. USE

4.1 Recommendations for ir measurements
●
If the measured surface target diameter is less than 2"/50mm Ø,
then place the sensor as close as possible to the target surface
(<20"/50cm away). See Field of View (FOV) information under
Specifications.
●
If the target surface is covered with frost or any matter, clean it
before taking a measurement.
●
If the target surface is highly reflective put some matte tape, or
matte paint, over it before measuring.
●
If the Thermometer is erratic, or seems not to be measuring properly,
make sure that the sensor is clean and not covered by condensation.

Operating method

4.2.1 Infrared operation
1. Press and hold the yellow measurement button - MEAS. The
thermometer will display SET briefly on the main display while it auto-
checks.
2. Aim the Thermometer towards the target.
3. If using the aiming laser, remove the laser cover, and press the
Button to turn the laser ON and OFF. The laser will go on
when MEAS is pressed.
4. Infrared thermometer sensors need a certain time to stabilize to
ambient temperature. Remember to let the IR meter reach ambient if
brought in from different temperature environment.
5. Press the button to turn ON the backlit.
6. If the measured temperature is outside the measurement range, OL
will be displayed.
7. The thermometer will continue measuring as long as the MEAS button
is pressed. When the button is released the measurement will be held
in the display for 15-20 seconds. HOLD is displayed in the lower left-
hand corner of the display.
8. The IR thermometer will shut OFF automatically after 15-20 seconds.
4.2.2 K Thermocouple operation
1. Connect the K thermocouple to the instrument input.
2. Press MEAS to turn the thermometer ON
3. Press the MODE button (six times) to enter the thermocouple mode.
K will be displayed in lower right hand corner of the display.
4. Put the thermocouple near or on the sample tested.
5. Press MEAS button to measure. Thermocouples need a certain time
to respond. Take the reading when the measurement has stabilized.
The reading is displayed in the smaller lower display in front of the K
symbol. The main larger display is the IR temperature reading.
6. The thermometer will continue measuring as long as the MEAS button
is pressed. When the button is released, the measurement will be
held in the display for 15-20 seconds.
7. When finished, remove the thermocouple from the sample, and unplug
the thermocouple from the meter. The thermometer will shut OFF
automatically after 15-20 seconds.
Note: IR measurements are active at the same time as the K t/c
measurements.
