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 and 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 diodes 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.
6.8. Checking Continuity
Follow these steps to check a circuit’s continuity.
1. Set the rotary selector to (((o)))
2. Plug the b
lack test lead into your meter’s COM terminal
and
the
red
test
lead
into
your
meter’s
V/
/CAP/Hz/Temp.- terminal.
3. Remove power from the circuit.
4. Connect the test leads to the circuit.
Note:
The buzzer sounds if the measured resistance is below about
50
approximately.
