Operation CHARM: Car repair manuals for everyone.
Manuals through 2025 now available!

Our trusted friends have launched a new website named LEMON, which has newer manuals. It also contains all the CHARM manuals.

LEMON is the spiritual successor to CHARM, I recommend you try it!

Digital Volt/Ohm Meter (DVOM)





PURPOSE
A Digital volt/ohm meter, can be used to measure and compare actual values with expected circuit values.

DIGITAL METERS VERSUS ANALOG METERS
Digital volt/ohm meters have a numerical readout, which is more precise than the needle reading on an analog meter.

Digital volt/ohm meters have a higher internal impedance (10 Meg ohms typical), which prevents loading or damaging digital (computer related), circuits.

VOLTMETER CAUTION: When measuring voltage always connect meter in parallel to a circuit or component. Connecting a voltmeter in series with a circuit may damage the voltmeter and/or the circuit.

OHMMETER CAUTION: Always disconnect any voltage sources from the circuit or component, before attempting to measure resistance of a circuit or component. Connecting an ohmmeter to a circuit while voltage is present will damage the meter and/or the circuit.
