How do you read a digital multimeter

What happens if you switch the red and black probes? The reading on the multimeter is . If you prefer, you can use the touch-hold feature to keep the reading on the display after you remove the probes. Advanced multimeters might have other functions, such as the ability to . Press the relative (REL) button to set the multimeter to a.

For more information on the basics of Digital Multimeters , see our online course available at the Fluke eLearning Center.

It will also explain the basics of electricity and address .

Digital multimeters (Photo 2) have LCD readouts and do continuity testing. Some digital multimeters also feature auto- ranging and . A digital ohmmeter (or ohm meter ) is useful for measuring circuit resistance in electrical components. Digital ohm meters are far easier to read and use than their analog counterparts. Many newer multimeters have digital readouts, rather than the analog scale.

The meter will read one of three things, 0. In this case, the meter reads 0. Ohm mode so you need to move the decimal three places to the right or 9Ohms). Click the link below for the lowest prices on. How to measure resistance with an digital multimeter , DMM. The position of the test leads is arbitrary.

Note that the component may need to be isolated from other components in the circuit. If the circuit is open (the switch is in the OFF position), the DMM will not beep. When finishe turn the multimeter OFF . Read the measurement in the display.

The abbreviation Hz should appear to the right of the reading. If voltage in the circuit is unknown, set the range to highest voltage setting. Note: Most digital multimeters power up in Autorange mode, . A multimeter is used to make various electrical measurements, such as AC and DC voltage, AC and DC current, and resistance.
