Caution:
a. Disconnect circuit power and discharge all capacitors before you test
capacitance.
Measure Diode
1. Connect the black test lead to the COM Terminal and
connect the red test lead to the VHz Terminal;
2. Turn the rotary switch to the Capacitance Mode;
3. Connect the red probe to the anode side and the black
probe to the cathode side of the capacitor being tested;
4. Read the measured capacitance value on the display
once the reading is stablized.
Caution:
a. Do not input voltage at the Diode Mode.
b. Disconnect circuit power and discharge all capacitors before you test diode.
Measure Frequency and Duty Cycle
Measure Temperature
1. Connect the black test lead to the COM Terminal and
connect the red test lead to the VHz Terminal;
2. Turn the rotary switch to the Voltage(mV) Mode; press
SELECT twice to toggle to the Frequency Mode or press
SELECT three times to toggle to the Duty Cycle Mode;
3. Touch the probes to the desired test points of the circuit;
4. Read the measured frequency/duty cycle value on the
display.
1. Connect the black thermocouple probe to the COM
Terminal and connect the red thermocouple probe to the
VHz Terminal;
2. Turn the rotary switch to the Temperature Mode, and the
display will show the room temperature, to toggle between
Caution:
a. The Frequency Mode only applies to measure high frequency with low voltage.
