English
2. Set the rotary switch to %Hz position.
3. Push θHz button to select Hz or Duty Cycle function. Displays shows Hz or %.
4. Connect the test leads across with the object being measured. The measured
value shows on the display.
5. When meter is on V or A measuring mode frequency or duty cycle can be
measured by pushing θHz button.
Diode test
(See fig 2)
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 a diode out of a circuit, connect as follows:
1. Insert red test lead into the VΩHz terminal and black test lead into the COM
terminal.
2. Set the rotary switch to diode position.
3. Push select button to select diode function. Displays shows diode symbol.
4. 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.
