ESSENTIAL ELECTRICAL CONCEPTS
Available Voltage:
•
The meter probes are
placed to test the
available voltage at
the switch.
Measure available voltage using a digital multimeter with these steps:
1. Set the mode selector switch to Volts DC.
2. Select the Auto
−
Range function or manually set the range.
−
Because the battery supplies available voltage in automotive circuits, you will typically
measure voltages between zero and 12 to 14 volts.
−
For other DMMs, set the range to the value closest to and higher than 12 volts.
3. Connect the voltmeter leads in parallel with the circuit element to be tested.
−
Red lead closest to the battery (connect first).
−
Black lead to a good ground.
4. Read measurement on DMM display.
−
Note polarity.
−
Correctly apply units.
NOTE:
The meter leads are most likely reversed if the DMM display indicates
negative polarity. It could also mean there is a fault in the circuit.
