Frequency/Duty Ratio Measurement - UYIGAO 19B User Manual

The meter's capacitance range is: 60.00nF、600.0nF、
6.000uF、60.00 uF、600.0 uF、6mF、100mF。
1）Turn the rotary switch to 100mF.
2）Insert the black test lead into the COM jack, and the
red test lead into the
3) After the capacitor is fully discharged, connect the
other end of the red and black test leads to the two ends of
the capacitor under test. The measured capacitance value
is read by the liquid crystal display.
Note：
1) To improve the accuracy of measurements below 10nF,
subtract the distribution capacitance of the meter and
leads.
2) When measuring large capacitance, stable reading
takes a certain amount of time.
3) When measuring polar capacitor, pay attention to the
corresponding polarity to avoid damaging the instrument.
4.14 Frequency / Duty Ratio Measurement
1）Through the AC voltage gear：
Warning
Risk of electric shock.
Pay special attention to avoid electric shock when
measuring high voltage. Do not enter voltages above
750V RMS to prevent electric shock or damage to
the meter.
Do not apply voltages in excess of 750 V RMS
between the common terminal and earth ground in
case of electric shock or damage to the meter.
1) Put the changeover switch in the proper AC voltage
jack.
