The multimeter is one of the most useful tools
in the toolbox. It can be used to check wires,
shorts, voltages, resistance, all manner of
electrical circuits. This tutorial is designed to
help clarify the symbols and socket options
found on various multimeters.
Probes connect the meter to the circuit. Sim-
ply touch them to the connections you want
to measure and read the display. Obviously,
this depends on how the meter is set up, and
what is being measured.
The Common Port.
1.
Generally, the black probe plugs in here
(negative) and as the name suggests, it’s
the common element to all of the testing
circuits. Think of it as the ground rail.
Voltage, Resistance and Continuity port.
2.
This is commonly used option. Connect
the red (positive) probe to this port when
using any voltage readings, resistance
readings or when checking wire continu-
ity (explained in more detail later in the
tutorial).
Current up to 300mA.
3.
This port is used for “counting electrons”
in a circuit, and thus their rate of
fl
ow
(current being the
fl
ow of electrons).
You’ll notice that this side is “fused”, so
that you don’t end up melting the meter’s
circuits.
Current up to 10A.
4.
Same as above, except it can take
more current, as the name suggests.
