4.3.1. DC Voltage measurement
CAUTION
The maximum input for DC voltage is 1000V. Do not attempt to measure
higher voltages to avoid electrical shocks or damages to the instrument.
Fig. 2: Using the meter for DC Voltage measurement
1. Selecting the position V .
2. Pressing the R/SEL key to select the correct range or using the Autorange feature (see
§ 4.2). If the voltage value under test is unknown, select the highest range.
3. Insert the test leads into the jacks, the red plug into V Hz
A jack and black plug
into COM jack
4. Connect the red and black test leads to the positive and negative poles of the circuit
under test respectively (see Fig. 2). 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 § 4.2.
