Measurement Operation(3)
The AC voltage measurement has 4 measurement
positions on the rotary switch: 2V, 20V, 200V and 750V
To measure AC Voltage, connect the Meter as follows:
1. Insert the red test lead into the V
and 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.
l The LCD displays "1" indicating the existing selected
range is overloaded, it is required to select a higher
range in order to obtain a correct reading.
l When AC voltage measurement has been completed,
disconnect the connection between the testing leads
and the circuit under test.
