How to Read a Fluke Digital Multimeter

Fluke digital multimeters perform a variety of measurement functions. They can measure voltage, current and resistance. By selecting the correct function on the selector knob, the measurement can be made and read on the digital display. Fluke digital multimeters have large digital displays, making the numbers easy to read. This makes it much easier than analog multimeters, which make measurements by a needle being deflected across a dial face. For whichever type of measurement you need, a Fluke digital multimeter can provide the reading that you're looking for.

Things You'll Need

• Multimeter probes

Instructions

1. Connect the probes to your Fluke digital multimeter. Probes are color coded red and black. There are separate jacks for measuring current, so make sure you know which type of measurement you're going to make when plugging in your probes. Match the colors between the probe banana jacks and the input plugs. Insert the black banana jack into the negative or common plug, and insert the red banana plug into the positive plug.

2. Turn your multimeter on. Turn the function dial to the function you want to use. Fluke digital multimeters have automatic range circuitry, so all you need to do is select the function. Select resistance, current or voltage.

3. Touch the probes to the metal contacts from which you want to take a measurement. Keep your hands on the plastic insulation part of the probes for safety reasons.

4. Read the number directly on the Fluke multimeter's display. The number is the value that is being measured at the tips of the probes. For voltage, the number will be in volts. For current, the number will be in amperes. For resistance, the number will be in ohms. Watch the decimal point for numbers and values less than one.

5. Remove the probes from the measurement source and turn off the Fluke digital multimeter. Write down the measurement if you're worried about forgetting the reading.

Tips & Warnings

• Keep a bowl nearby when working on home electrical repairs so you can keep parts in the bowl and not lose parts.

• Be careful when working with electrical voltages. They can be extremely dangerous and cause electrical shock.
