How to use the multimeter to check electric systems
Multimeter operation
This instrument can take resistance, voltage and current values. Multimeters are usually gathered into
two big families: analogue and digital display multimeter. An analogue multimeter has a pointer
display. Display dial shows different measurement scales. Digital ones have a dial on which digits for
taken value are indicated. A selector or a set of outlets for both terminals allow you to set unit of
measurement, i.e. volt, ampere or ohm. Sometimes the full scale value should also be set. If a voltage
value of 12V needs to be taken, select a full scale which is as close as possible to this value: for
example 15V or 20V. A 10V full scale is not correct. The same applies if amperes or ohm values should
be taken. Sometimes the instrument automatically sets the full scale value. Never exceed the max.
value allowed by the instrument when measuring volts or ampere.
Note
The "DDS" can also work as digital multimeter.
How to measure voltage
Always connect multimeter terminals in parallel with the power supplied part, for example with two
wires to a lamp, to a relay, to a control unit or with both battery poles. Voltage values are constant
over time for direct voltage or variable for alternate voltage. Direct voltage include a negative and a
positive pole. For this reason, also the type of voltage should be selected on the multimeter. (= is the
symbol for direct voltage; ~ is the symbol for alternate voltage).

DDS diagnosis instrument, as far as "DDS" tester is concerned.
