Imprimir páginapolarity of the red meter pen wire and the tested voltage value are spontaneously displayed on the display.
Caution:
a）Voltages over DC1000V or AC750V cannot be tested.
b) When measuring high voltages, special precautions must be taken to avoid
electrical shock.When measurement is completed, immediately disconnect
the meter pen and the measured circuit.
c) In case "OL" is displayed for manual range mode, it indicated the range has been
exceeded and it is necessary to select higher range mode to complete this measurement.

Input impedance: 600mV range>60MΩ，the others are 10MΩ. Overload protection: 1000VDC or 750V alternative peak.
IX. AC Voltage (ACV)
1.Circularly press the "AC/DC" key until it selects the AC Voltage automatic measurement mode. Meanwhile, the symbol
"AC" ， "AUTO" ， "APO"will appear on the LCD. Respectively plug in the red and black meter pens into the terminals
of "
" and "com". See the picture below.
2.The initial state of the meter is automatic range, which shows "AUTO" symbol.
Press the "Range" key and switch it to manual range mode. In the AC mode of
automatic/manual range, the frequency/ duty cycle can be measured by
pressing "Hz/DUTY". However, the frequency response now is low ,
which is suitable for the measurement of high voltage and low frequency
in the environment of magnetic field interference such as 220V/50Hz-400Hz,
380V/50Hz－400Hz.
Caution:
Voltages over DC1000V or AC750V cannot be tested. In case "OL" is displayed for manual range mode,
it indicated the range has been exceeded and it is necessary to select higher range mode to complete this measurement.
