1. Press INPUT/OUTPUT key and select the measurement mode. The “INPUT” symbol is
displayed
2. Press V/mV key and select the desired measurement unit. The symbol “V” or “mV” is
displayed
3. Insert the red plug into V jack and the 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 will be displayed
5. The message "O.L" means that the voltage exceeds the measuring limits. The symbol
"-O.L" on the display means that voltage has opposite polarity respect the connection
shown in Fig. 2
