Ac Voltage Measurement - UNI-T VC820 Operating Manual

VC820/VC840 OPERATING MANUAL
The measured value shows on the display.
In each range, the Meter has an input impedance of 10MΩ. This loading effect can cause measurement errors in high
impedance circuits. If the circuit impedance is less than or equal to 10kΩ, the error is negligible (0.1% or less).
When DC voltage measurement 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.
B. AC Voltage Measurement
Warning
To avoid harms to you or damages to the Meter from electric shock, please do not attempt to measure voltages
higher than 1000V / 750V TRMS although readings may be obtained.
The AC Voltage ranges are: 400.0mV, 4.000V, 40.00V, 400.0V and 750V. To measure AC Voltage, connect the Meter as
follows:
1. Insert the red test lead into the HzV
2. Set the rotary switch to
3. Connect the test leads across with the object being measured.
