4.7. Capacitance Measurement
1. Apply the knob to proper capacitance range, and insert the measuring accessories or test leads
into “COM” and “mA” terminal. Note: “COM” terminal is for positive pole (+), “mA” terminal is (-)
2. Connect test leads with the two points of capacitor, be wary of polarity if necessary.
NOTE:
1. If the capacitance under tested is over the max. value of selected range LCD displays “1”, thus,
should set the knob to a higher range.
2. When measuring at large capacitance range, if capacitor is crept badly or broken, LCD displays
a value and it’s unstable.
3. Release the capacitor completely before measuring.
4.8. Transistor hFE
1. Set the knob to hFE range. Inset the test leads to “COM” and “mA” Note: “COM” terminal is for
positive pole (+), “mA” terminals is (-).
2. Verify the transistor under tested is NPN or PNP, insert emitter, base and collector to proper
jack.
4.9. Diode and Continuity Test
1. Apply the black test lead to “COM” terminal and the red one to “V/ Ω ” terminal (the polarity of
red lead is “+”).
2. Set the knob to range, connect test Leeds with the diode dunder tested, the red test
connect to diode positive polarity, the reading is approx. value of diode forward volt drop.
3. Apply test leads to two points of tested circuit, if the inner buzzer sounds, the resistance is less
than (70
±
20)
Ω
4.10. Hot Wire Test
1. Pull out the black test lead from “COM” jack, and set the red one to “V/
Ω ” jack.
2. Set the knob to TEST range, and set the red test lead to the tested circuit.
3. If LCD displays “1” and the light and sound alarming, it means the circuit of the red test lead
tested is hot wire, if there is no any response, it means it is neutral wire.
