MEASUREMENTS

4.3.1. DC Voltage measurement

The maximum input for DC voltage is 600V. Do not attempt to measure
higher voltages to avoid electrical shocks or damages to the instrument.
1. Selecting the position 200mV
2. Insert the test leads into the jacks, the red plug into VmAA
into COM jack
3. 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
4. If the message "OL" is displayed select a higher range.
5. The symbol "-" on the instrument display indicates that voltage has opposite direction
with regard to the connection.
6. For HOLD function refer to § 4.2.1
