How do you use a multimeter?
A multimeter is a very useful instrument if you want to get serious about electronics. By means of a multi-selector switch, the meter can be set to measure resistance, voltage or amperage. Some multimeters even have settings that can measure diodes, transistors and frequencies.
A multimeter also has different measurement modes for each measuring subject, within which measurements can be taken. For example, voltage can be measured in both alternating current (AC) and direct current (DC).
Choosing a multimeter
A cheap multimeter is perfectly suitable for general use in your electronics projects. Such a digital multimeter is the best choice as a first multimeter. Even the cheapest multimeter is perfectly suitable for testing simple projects.
Digital multimeters
All digital meters contain a battery to mainly power the display. So they actually use almost no energy from the circuit you are testing. This means that they have a very high resistance value at the DC voltage. This is also called input impedance. This impedance is 1M or higher and often even 10M. This makes it very unlikely that a measurement will disturb the circuit under test and that is exactly what you need.
Typical measuring ranges for digital multimeters are: (the maximum values given are the maximum values per measuring range) * DC Voltage: 200mV, 2000mV, 20V, 200V, 600V. * AC Voltage: 200V, 600V. * DC Current: 200µA, 2000µA, 20mA, 200mA, 10A*. * AC Current: none. (normally you don't need this either) * Resistance: 200, 2000, 20k, 200k, 2000k, Diode Test.
