Ac Voltage Measurement - UNI-T UT90A Operating Manual

Model UT90A: OPERATING MANUAL
Measurement Operation(3)
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 DC/750V AC although
readings may be obtained.
The AC voltage ranges are: 2.000V, 20.00V, 200.0V and
750.0V.
To measure AC Voltage, connect the Meter as follows:
1. Insert the red test lead into the V
the black test lead into the COM terminal.
2. Set the rotary switch to an appropriate measurement
position in V
3. Connect the test leads across with the object being
measured.
The measured value shows on the display, which is
effective value of sine wave (mean value response).
Note
l If the value of voltage to be measured is unknown,
use the maximum measurement position (750V) and
reduce the range step by step until a satisfactory
reading is obtained.
