If the screen displays 1 or OL (open loop), there's no continuity—that is, there's no path for electric current to flow from one probe to the other.
What is infinity on a multimeter?
On a VOM, infinity signifies an open circuit. On an analog multimeter, infinity shows up as an unwavering needle that won't move off the far left side on the display. On a digital multimeter, infinity reads “0. L.” On a VOM, “zero” means a closed circuit has been detected.
What does OL mean on a fieldpiece multimeter?
For example, when measuring 24VAC, the meter will select the 40VAC range and display "24.0". In the 400Vrange, you'd see "24" and in the 4V range you'd see "OL" for over- load. When an n (nano), m (micro), m (milli), K, or M shows up in the display, you must multiply by 10-9, 10-6, 10-3, 103, and 106 respectively.
How do you read 200K ohms on a multimeter?
With the test lead probes still shorted, switch to each resistance range in turn and the decimal point should move position as follows: 200 Ohm = 00.1, 2k Ohm = . 000, 20k Ohm = 0.00, 200k Ohm = 00.0, 2M Ohm = . 000, 20M Ohm = 0.00. (1k Ohm = one thousand Ohms, 1M Ohm = one million Ohms).Feb 16, 2001

How do you reset a multimeter?
- Set the multimeter to the highest resistance range by turning the dial to the highest "ohm" setting.
- Touch the test probes of your digital multimeter together. ...
- Press the calibration knob until the display reads "0" on the digital multimeter if you don't see "0 ohms" initially.

How do you maintain a multimeter tester?
- Calibrate the multimeter at frequent intervals.
- Protect the instrument from dust, fumes, moisture and heat.
- Renew ohmmeter batteries.
- When checking the resistance of the circuit, make sure the switch off the power to the circuit.
Can I damage my multimeter?
You can avoid damaging your digital multimeter by anticipating the signal level you'll measure and presetting the proper signal range on the DMM. Overpowering the digital multimeter can damage the components inside the meter.

What can you do with multimeter?
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.
