3. Plug the black test lead into your meter’s COM terminal and
the red test lead into your meter’s V//Hz/ -terminal.
4. Connect the test leads to the diode you want to check and
note the meter reading.
Notes:
* If the display shows a value for example 0.2 for a
germanium diode or 0.5 for a silicon diode, reverse the
diode. If the meter indicates an overrange, the diode is good.
The displayed number is the diode’s actual forward voltage
(up to 2.0 volts).
* If the display indicates an overrange condition, reverse the
polarity of the connection. If the display shows a value, the
device is good. The displayed value is the component’s
actual forward voltage (up to 2.0 volts). If the display still
indicates an overrange condition, the device is open.
* If the display shows a value both before and after you
reverse the polarity, the device is shorted.
When you connect the diode to the meter and the meter displays
the devices forward voltage, the red test lead is connect to the
diode’s anode, and the black test lead is connected to the
diode’s cathode.
This meter supplies enough forward voltage to light most LED´s.
However, if the LED’s forward voltage is greater than 2.0 volts,
the meter incorrectly indicates that the device is open.
6.5. Checking Continuity
Follow these steps to check a circuit’s continuity.
1. Set the rotary selector to (((o)))
2. Plug the black test lead into your meter’s COM terminal and
the red test lead into your meter’s V//Hz/ - terminal.
