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 DCV Measurement is autoranging, the Meter has an input impedance of approx.
10MW. This loading effect can cause measurement errors in high impedance
circuits. If the circuit impedance is less than or equal to 10kW, 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.
