2.3.10 Temperature Measurement

Both thermocouple and thermal resistance types of temperature sensor are supported by UT8805E. The
connecting and measurement methods are shown below:
Steps:
1) Press
button and then press
Figure 2-27.
2) Connect the test leads to the sensor as Figure 2-28. Please be aware of the polarity of thermocouple
probe and don't reverse connect.
3) Select temperature probe
Press [Probe] to select the probe type: [RTD 2W], [RTD 4W], [Thermis2W], [Thermis4W] and [Tcouple].
The RO value of RTD is 100Ω by default which can be selected and manual modified in menu. The
relevant Steps of UT8805E thermocouple are: press [Tcouple] to enter the menu, select thermocouple
type in [Type], set offset value in [Offset Adjust] by direction buttons, and select proper temperature
reference in [Reference] (internal NTC sensor by default).
4) Relative value setting
