junction adjacent to the thermocouple jack.when using external reference mode, The fixed reference temperature
value(range: ‐10 to 50 ℃ )must be entered manually before
thermocouple measuring. Figure 8.9 shows the thermocouple
measurement connections.
To measure temperature by using thermocouple simulation, proceed
as follows:
1. If measurement is active, press
once, otherwise press
twice.
2. You can press the navigation keys Up/Downto select the first item
from the pop‐up list, then press Enter orDoneto change then
measurement or pressthe Optionsto show thermocouple
measurement setup interface. In the thermocouple measurement
setup interface, you can set the thermocouple sensor type,
temperature units(℃, K,℉) and reference junction compensation
methods.
3. When thermocouple measuring, you can pressOptionsto show the
thermocouple measurement setup interface to set the
measurement settings.
4. To get higher temperature measurement precision, you can zero
measured value in millivolts measurement.
