Ammeters
It clearly follows that the function of an ammeter is to measure that current within an electrical circuit. Ammeters measure current in two metrics - ''draw'', the flow of current in a particular circuit, and ''continuity'', the steadiness of the current and the presence or absence of interruptions.
3 Ways to Connect an Ammeter
For instance, if you have the ammeter between a battery and a lightbulb, the red probe may connect to the lightbulb. The black wire can touch the battery''s negative terminal or a wire connected to it. If you''re working with a battery, don''t connect both probes directly to the battery''s terminals. It may cause the ammeter to burn out.
3 Ways to Measure Voltage
Set the range to one level above the voltage you plan to measure, so if you are measuring a 12v battery, turn the dial to 20v to get an accurate reading. X Research source If you choose a range that is too low for your test, the multimeter will display a "1", indicating that you need to choose a higher range.
