B. DC millvoltage Testing (see gure 5)
Warning
To avoid harms to you or damages to the Meter from electric shock, please do
not attempt to measure voltages higher than the range although readings may be
obtained.
When AC voltage measurement has been completed, disconnect the connection
between the testing leads and the circuit under test.
To measure DC millvoltage, connect the Meter as follows:
1. Insert the red test lead into the V terminal and the black test lead into the COM terminal.
2. Set the rotary switch to an appropriate measurement position in .
3. Connect the test leads across with the object being measured.
The measured value shows on the display. Press Hz button to obtain the frequency
value, input amplitude and frequency response refer to accuracy specications.
4. The Meter has an input impedance of approx. 4000MΩ.
