Testing for Continuity
To test for continuity, connect the Meter as below:
1. Insert the red test lead into V terminal and the black
test lead into the COM terminal.
2. Set the rotary switch to .
3. Connect the test leads across with the object being
measured.
4. The buzzer does not sound if the resistance of a
circuit under test is <70 .
The tested circuit resistance value simultaneously
shows on the display and the unit is .
2. Set the rotary switch to .
3. For forward voltage drop readings on any semiconductor
component, place the red test lead on the component’s
anode and place the black test lead on the component’s
cathode.
The measured value shows on the display.
Measuring Diodes
Use the diode test to check diodes, transistors, and other
semiconductor devices. The diode test sends a current
through the semiconductor junction, and then measures
the voltage drop across the junction. A good silicon junction
drops between 0.5V and 0.8V.
To test out a diode out of a circuit, connect the Meter as
follows:
