Diode Measurement - UNI-T UT8805E Manual

The short circuit defaulted value is 30Ω, and can be set by direction buttons. Users can carry continuity
test directly if this parameter is no need to be modified.
The characteristics of continuity test:
Test current
Range
Open circuit voltage
Input protection
Beeper condition
3) Beeper setting
Press [Beeper] to turn the beeper function on or off. If the circuit is connected, the beeper will continuously
beep.
4) Test the testing point and read the displayed value.

2.3.9 Diode Measurement

Diode measurement uses 2-wire mode to measure the break-over voltage of circuit at a current of 1mA.
The connecting and measurement methods are shown below:
1) Press button and then press
25.
2) Connect the test leads to the measured circuit by connecting the red test lead to terminal Input-HI,
and the black one to terminal Input-LO as Figure 2-24.
