Diodetest; Capacitance Measurement - KPS MT50 Manuel D'instructions

3.2.3 Diode test
Use the diode test to check diodes, and other semi- conductor
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:
1. Set the rotary switch to
2. Press the FUNC key one time to ativate Diode Test.
3. Connect the black and red test leads to the COM and
respectively.
4. For forward-bias 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
5 The meter will show the approx. forward voltage of the diode. If the test lead
connection is reversed, only figure "OL" displayed.
In a circuit, a good diode should still produce a forward bias reading of 0.5V to
0.8V; however, the reverse-bias reading can vary depending on the resistance
of other pathways between the probe tips.
3.2.4 Continuity Check
Continuity is a complete path for current flow.
The beeper sounds if a circuit is complete. These brief contacts cause the
Meter to emit a short beep.
To test for continuity:
1 Set the rotary switch to
2. Press the FUNC key twice to activate Continuity Check.
3. Connect the black and red test leads to the COM and Ω terminals respectively.
4. Connect the test leads to the resistance in the circuit being measured.
5. When the test lead to the circuit is below approx. 60Ω, a continuous beeping
will indicate it.
Note:
- Continuity test is available to check open/short of the circuit..
