What are the units on a multimeter?
What are voltage, current, and resistance?
| Variable | Symbol | Unit |
|---|---|---|
| Voltage | V | Volts |
| Current | I | Ampere |
| Resistance | R | Ohm |
What is 2M on multimeter?
200k Ohm is 00.0, 2M Ohm is. One thousand Ohms is one million Ohms. Before we can use a multimeter to record resistance readings, we need to check the accuracy of each range against a known resistance value.
How can you find out the resistance of a multimeter?
Look at the range setting that the dial of your multimeter is set to. This should give you a number to multiply the reading by. For example, if the multimeter is set to R x 100 and the needle points to 50 ohms, the actual resistance of the circuit is 100 x 50 = 5,000.

How do you read a multimeter on an AC system?
To read a multimeter on an AC system, you’ll need to locate the numbers and symbols on your circuit system. On an AC circuit, for example,V stands for “voltage,” while a squiggly line indicates the alternating current. If you want to test a DC circuit, switch the setting on your multimeter to VDC or DCV.
What are the lines between two numbers on a multimeter?
The lines between two numbers still represent even divisions. For example, if there are three lines between “50” and 70,” these represent 55, 60, and 65, even if the gaps between them look different sizes. Multiply the resistance reading on an analog multimeter. Look at the range setting that the dial of your multimeter is set to.
