5.3 Voltage Measurement

1. Turn Selector Dial to Voltage Mode (V position)
2. Select Voltage Mode then press
3. Connect probes to circuit to be tested red=positive(+), black=negative(-)
4. Display will then show correct voltage
While measuring voltage, the Status Indicator will also illuminate to give a quick indication of correct voltage for 5V, 12V or 24V power sources
For example when measuring voltages from a vehicle ECU
