3. 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.
Note
••
In a circuit, a good diode should still produce a forward
Measurement Operation (6)
Voltage drop reading of 0.5V to 0.8V; however, the reverse voltage drop reading can vary depending on the resistance of other
pathways between the probe tips.
••
Connect the test leads to the proper terminals as said above to avoid error display. The LCD will display indicating diode being
tested is open or polarity is reversed.The unit of diode is Volt (V), displaying the forward voltage drop readings.
••
When diode testing has been completed, disconnect the connection between the testing leads and the circuit under test, and
remove the testing leads away from the input terminals of the Meter.
F. Capacitance Measurement
(see figure 8)
Warning
To avoid damage to the Meter or to the equipment under test, disconnect circuit power and discharge all high-voltage capacitors
before measuring capacitance. Use the DC Voltage function to confirm that the capacitor is discharged.
The Meter’s capacitance ranges are: 40.00

as follows:
1. Insert the red test lead into the HzV

terminal and the black test lead into theCOM terminal.
2. Model UT60C Set the rotary switch to
