4.3 Measurements

4.3.1 DC Voltage measurement

The maximum input for DC voltage is 1000V. Do
not attempt to measure higher voltages to avoid
electrical shocks or damages to the instrument.
1. Selecting the position V
2. Pressing the R/SEL key to select the correct range or using the Autorange feature (see
paragraph 4.2.4). If the voltage value under test is unknown, select the highest range.
3. Insert the test leads into the jacks, the red plug into
jack (see Fig. 2).
4. Connect the red and black test leads to the positive and negative poles of the circuit under test
respectively. The voltage value is displayed.
5. If the message "O.L" is displayed select a higher range.
6. The symbol "-" on the instrument display indicates that voltage has opposite direction with
regard to the connection.
7. For HOLD function, Minimum and Maximum value measurement and Relative measure please
refer to paragraph 4.2.
