Hey Steph, don't be afraid. It is easy to use a volt meter. The setting on
the knob will indicate the scale of the reading. At this point, you are
able to ignore all of the amp settings. A volt is the amount of electrical
"pressure". Think of a hydraulic circuit, PSI is a measure of hydraulic
pressure, PSI = pounds per square inch, volts = electrical pressure. Our cars
have
12 Volts of electrical pressure from the battery. IN order to complete a
circuit and have something happen, (i.e. a lamp light), the electric circuit
must go from the battery to the earthing point, positive (+) to negative (-).
If a circuit is "grounded" before the circuit is completed, the action will
not happen.
The ohm scale on your meter tells the amount of resistance to circuit flow,
measured in ohms. The closer you get to ground/earth/negative the lower the
ohm reading. Does this help? Let me know and perhaps we can talk on the
phone. Electronics is my game. Regards, Tom
