How to Use a Multimeter (with Pictures)
An ammeter is placed in series with the circuit to measure current. It cannot be placed "across" the circuit the way a voltmeter is used (otherwise the meter will probably be damaged). Observe the polarity. Current flows from the positive side to the negative side. Set the range of current to the highest value.
Voltmeter
The most basic type of DC analogue voltmeter is the "permanent-magnetic moving-coil" (PMMC) meter, also known as a D''Arsonval movement. This type of analogue meter movement is basically a current measuring device (termed galvanometer) which can be configured to operate as either a Voltmeter or as an Ammeter, the principal difference is the way in which they are connected …

Measuring Voltage, Current, and Resistance
Most multimeters and traditional ammeters measure current in series with the points being measured. This means that you have to de-energize the circuit, insert the ammeter into the circuit between the measurement points, and then re-energize the circuit. Clamp-on ammeters have the capability of measuring current running through a clamp.
