Place one probe at each end of the circuit or component you want to test. It doesn’t matter which probe goes where; resistance is non-directional. If your multimeter reads close to zero, the range is set too high for a good measurement. Turn the dial to a lower setting.
On this type of multimeter, start by selecting the highest voltage on the dial and then turn down to a lower voltage if the voltage measured is seen to be low. If you are measuring a single battery cell and you know that it is a 1.2V or 1.5V cell, then you can start by setting the multimeter dial to 2V or 20V.
A multimeter is a handy tool that you use to measure electricity, just like you would use a ruler to measure distance, a stopwatch to measure time, or a scale to measure weight. The neat thing about a multimeter is that unlike a ruler, watch, or scale, it can measure different things — kind of like a multi-tool.
Alternating Current (AC)
A symbol that has a capital ¨A¨ with a squiggly line above it represents the Alternating current catch.
To test for a live electrical wire either a non-contact voltage tester or a digital multimeter is used. A non-contact voltage tester is the safest way for testing live wires, performed by placing the machine near the wire.
mAVΩ is the port that the red probe is conventionally plugged in to. This port allows the measurement of current (up to 200mA), voltage (V), and resistance (Ω). The probes have a banana type connector on the end that plugs into the multimeter.
Every dignified multimeter uses red for positive and black for negative. In addition to that, when you’re measuring volts, you can just switch the inputs. It won’t go wrong, you’ll just get a negative value.
AC means Alternating Current and DC means Direct Current. … An electrical signal is a voltage or current which conveys information, usually it means a voltage. The term can be used for any voltage or current in a circuit.
Batteries and electronic devices like TVs, computers and DVD players use DC electricity – once an AC current enters a device, it’s converted to DC. A typical battery supplies around 1.5 volts of DC.
direct current, abbreviation DC, flow of electric charge that does not change direction. Direct current is produced by batteries, fuel cells, rectifiers, and generators with commutators.

Multimeters are generally not autoranging. You have to set the multimeter to a range that it can measure. For example, 2V measures voltages up to 2 volts, and 20V measures voltages up to 20 volts. So if you’ve measuring a 12V battery, use the 20V setting.
When testing for continuity, a multimeter beeps based on the resistance of the component being tested. That resistance is determined by the range setting of the multimeter. Examples: If the range is set to 400.0 Ω, a multimeter typically beeps if the component has a resistance of 40 Ω or less.
3 Answers. If the multimeter is set to read voltage, it will have a very high-resistance, so if everything is working correctly touching the other lead will not shock you.
