Digital multimeter
test probes
• During continuity test, if the measured circuit resistance is not greater than
about 50Ω, the buzzer may issue continuous sound.
Diode test
When measuring continuity, press FUNC key to switch to diode test.
•
Respectively connect black and red test probes to COM input socket and Ω
input socket.
• Measure two ends of diode to be measured with other two ends of test
probes
• The meter will display the forward voltage drop value of the diode.
Capacitance Μeasurement
Capacitance range of this meter: 40.00nF, 400.0nF, 4.000μF, 40.00μF, 100.0μF
To measure capacitance:
• Rotate rotary switch to position.
• Respectively connect black and red test probe to COM input socket and
input socket.
• Measure the capacitance value of circuit to be tested with other two ends
of test probes and read the measuring value from LCD display.
Frequency And Duty Ratio Measurement
Capacitance range of this meter: 5Hz, 50Hz, 500Hz, 5kHz, 50kHz, 5MHz
To measure capacitance:
• Rotate the switch to Hz position.
• Respectively connect black and red test probe to COM input socket and Hz
input socket.
• Measure the frequency to be measured with other two ends of test probes
and read the measuring value from LCD display.
Current Measurement
Current range of this meter: 400μA, 4000μA, 40.00mA, 400.0mA, 10.000A;
• Cut off the power supply of circuit to be tested.
Discharge all high voltage capacitors on the circuit to be tested.
•
Rotate switch to the appropriate position (μA, mA or A grade).
• Connect the black test probe to the COM input socket. If the current to be
tested is lower than 600mA, connect the red test probe to the mA input
socket; if the measured current is between the range of 600mA~10A, the
red test probe should be connected to 10A input socket.
