Dc Voltage Measurement - UNI-T UT70C Operating Manual

Measurement Operation (2)
B. DC 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 rms although
readings may be obtained.
The DC Voltage ranges are: 8.000V, 80.00V, 800.0V and
1000V. To measure DC Voltage, connect the Meter as
follows:
1. Insert the red test lead into the
and the black test lead into the COM terminal.
2. Set the rotary switch to V
3. Connect the test leads across with the object being
measured.
The measured value shows on the display.
Note
l
In each range, the Meter has an input impedance
of 10M
measurement errors in high impedance circuits. If
the circuit impedance is less than or equal to 10k ,
the error is negligible (0.1% or less).
l When DC voltage measurement has been completed,
disconnect the connection between the testing leads
and the circuit under test.
