The Features of Fluke Meters

Auto-Polarity

• It can be time consuming to determine the polarity of a direct-current device or wiring scheme. Fluke multimeters offer the ability to correctly detect the polarity of the electrical device, regardless of whether the positive or negative probe is connected in concordance with the positive or negative pole on the device.

Auto-Ranging

• Electrical signals often fluctuate. Users of Fluke multimeters do not want or need to see these fluctuations, so Fluke designed their multimeters to lock onto the most appropriate range. Known as freezing, this feature selects the most appropriate decimal readings and eliminates hunting between ranges.

Large Display

• Many work areas are dark or dimly lit. Most multimeters have a black LED readout, but Fluke models offer a bright white readout, backlit for easy at-a-glance readings.

Low Input Impedance

• Ghost voltage is a phenomenon that makes taking accurate readings harder than it needs to be. Ghost voltage is present when a high-input impedance test instrument is among the devices emitting AC voltage, making it tough to determine if the voltage is coming from the device tested or an adjacent one. Low input impedance on the multimeter largely eliminates the multimeter's sensitivity to this spurious voltage.
