How to Read a Fluke Multimeter

Electricity is the flow of charged particles known as electrons. As the electrons flow through the wire, there are two quantities that are important: voltage (potential energy per unit charge ), and current (scaled velocity). These quantities can be measured using a portable device known as a Fluke multimeter. This consists of a main unit and two measurement probes. The device is capable of measuring voltage, current and resistance, each of which are frequently needed in appliance fault-testing,

Things You'll Need

Fluke multimeter

Instructions

- 1
  Plug the two measurement probes into the main unit. Two measurement probes are provided with Fluke multimeters. Plug the red probe into the positive terminal and the black probe into the negative terminal.
- 2
  Switch on the multimeter by rotating the dial on the front counterclockwise. Select the required measurement function by rotating the dial to the relevant position. There should be a choice of AC voltage, DC voltage, DC current, resistance and continuity. The screen on the multimeter should read "0.00."
- 3
  Place the measurement probes into contact with the electrical component that is being measured. The screen on the multimeter should now change to a series of numbers such as "1.75." Voltage is measured in volts/milli-volts depending on the selected function, current is measured in amps, and resistance is measured in Ohms. On the resistance setting if a small k appears to the right of the three numbers, this represents kilo-Ohms, so the reading to the left is in thousands of Ohms. If the continuity setting has been selected, the multimeter will make an audible beep if electrical continuity is present.
