Digital Volt Ohm Meter (DVOM)

DVOM:

REFER TO USERS MANUAL FOR COMPLETE INSTRUCTIONS


VOLTMETER
Voltage position measures magnitude of voltage when connected in parallel to an existing circuit. A digital voltmeter with a 10 megohm input impedance is used because this type of meter will not load down the circuit and result in faulty readings. Some circuits require accurate low voltage readings because they have a very high resistance.

AMMETER
When used as an ammeter, this meter accurately measures extremely low current flow. Refer to meter instructions for more information.

^ Selector must be set properly for both function and range. DC is used for most automotive measurements.

OHMMETER
Measures resistance of circuit directly in ohms.

- "OL" display in all ranges indicates open circuit.

- Zero display in all ranges indicates a short circuit.

- An intermittent connection in a circuit may be indicated by a digital reading that will not stabilize on the circuit.

- Range Switch - Automatic and Manual.
4OO ohms - Reads ohms directly. 4K, 40K, 400K ohms - Reads ohms in thousands. 4M, 40M, 400M ohms- Reads ohms in millions.
