7.7. TEMPERATURE MEASUREMENT WITH K-TYPE PROBE
WARNING
• Do not compare the infrared temperature measurement with the measurements
made with K-type thermocouples, since (because of the totally different nature
of the two methods) the obtained values may differ remarkably
• Measurement with the K-type thermocouple can be used in situations where IR
measurement cannot be used (e.g.: measurement of shiny/bright surfaces such
as glass and plexiglas)
1. Select one of the measuring modes “IR VIDEO” or “IR MEASUREMENT”, “DEW
POINT” or “DATALOGGER”
2. Activate the temperature measuring option with K-type probe (see § 6.10)
3. Connect the K-type probe to the corresponding inputs (see Fig. 1 – Part 10) respecting
the polarity marked on the instrument and on the probe.
4. Press the T key to start measuring. While measuring, the symbol is shown on the
display and the temperature value will be indicated as “TK”.
5. Release the T key to stop the measurement and freeze the last read value. The display
shows the following symbol “ ”. The temperature values associated with fields AT,
RH%, DP and WB, if selected (see § 6.8, 6.9) are shown on the display. The instrument
displays the values of the fields MAX, MIN, MED, AVG and DIF, if selected (see § 6.6,
6.7)
6. For the “IR VIDEO” mode press the arrow key to enter in the section of saving
temperature measurement with type K probe more than IR imagine and other
parameters (if selected) and press again the
S key to save or the T to exit without
save. For the “DATALOGGER” mode the data are automatically saved
