3.6 Hold Measurement
With Hold measurement, a stable reading can be remained on the display, even if the test leads are
removed.
Steps:
1) Press
button to enable DC voltage measurement and select proper voltage range.
2) Connect a test lead with the multimeter. Connect the red test lead to terminal Input-HI and the black
one to terminal Input-LO.
3) Press
→
to enter the interface of Hold measurement. The DC voltage will be recorded as
Figure 3-10.
4) Press
button to enable AC voltage measurement and select proper voltage range.
5) Connect a test lead with the multimeter. Connect the red test lead to terminal Input-HI and the black
one to terminal Input-LO. The AC voltage will be recorded as Figure 3-11.

3.7 Thermocouple Setting and Measurement
Thermocouple is common temperature sensor. The type, voltage and the cold junction temperature of
thermocouple is required in thermocouple measurement. With a built-in temperature sensor, UT8805E is
able to measure the temperature (cold junction temperature) near the terminal HI and terminal LO.
In thermocouple temperature measurement, the multimeter will automatically measure the cold junction
temperature and calculates the absolute temperature of the hot junction according to the cold junction
temperature.
In the setting of thermocouple sensor, according to the thermocouple type, users only need to input the
corresponding relationship between the thermocouple voltage and the temperature difference between
cold and hot junctions.
Steps:
1) Connect the sensor as
Chapter 2
. See Figure 3-12.
2) Ensure the type of thermocouple sensor.
