UT8805E Benchtop Digital Multimeter
24
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
1mA
Range
2kΩ fixed
Open circuit voltage
<8V
Input protection
DC 1000V OR AC 750Vrms (terminal HI)
Beeper condition
0
≤ R ≤ set value
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
button to enter interface of diode measurement as Figure 2-
25.
Figure 2-25 Interface of diode measurement
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.
