Types of Multimeter
There are two different types of multimeters: analog and digital. An analog multimeter uses an internal meter movement that measures current, voltage, or resistance. A digital multimeter has a numeric display to show measurements in numbers instead of having an internal moving part for each measurement function.
Multimeter Configuration Stages
Set the multimeter to measure the current after turning it on. There are three configuration stages:
Frequently Asked Questions About How To Use a Multimeter: Measuring Current (Amperage)
A multimeter must be inserted into a circuit to measure the current. First, turn the dial to the highest range of current (or 10A if you have a probe in a socket for 10A). If your meter is not auto range, set it to “A” or mA.
What is a voltmeter?
It's got a voltmeter for checking battery open circuit voltage. It also has a switch that turns on a very low-resistance dummy load. You use that to test how much short-circuit current the battery can put out. A meter like this is really handy if you're going to mess around with 6 and 12 volt batteries much.
How many volts does a 12 volt battery need?
A fully charged "12 volt" lead-acid battery is about 12.6 volts. (w'pedia) While charging you need to drive it at about 13.5 to 14 volts to make the current flow in. The battery will float high for a bit after charging, so voltage isn't great as an indicator of state-of-charge.
