Fluke 115 - True-RMS 600V Handheld Multimeter | Fluke

The Fluke FLUKE-115 is a compact true-RMS handheld digital multimeter (DMM) with a 6000-count, 3.75-digit LCD display and bar graph, measuring voltage from 600 mV to 600 V, resistance from 0.1 ohm to 40 MOhm, and current, capacitance, frequency, continuity and diode functions, with a basic accuracy of 0.1%. A digital multimeter (DMM) is a benchtop or handheld test and measurement instrument that converts analog electrical quantities - voltage, current, resistance, capacitance, and frequency - into a numeric reading. Within the test instrument hierarchy, the DMM sits alongside oscilloscopes and signal generators as a fundamental electrical troubleshooting tool, and true-RMS (root-mean-square) conversion distinguishes professional meters from average-responding meters by measuring the heating-equivalent value of non-sinusoidal and distorted waveforms accurately. Key features of the Fluke 115 include true-RMS AC voltage and current measurement for accurate readings on nonlinear loads, a 6000-count high-resolution display, Min/Max/Average recording to capture signal fluctuations, an analog bar graph for trend viewing, and convenience functions including backlight, data hold, and auto sleep for battery conservation. According to the Fluke detailed specification sheet, accuracy is specified for 1 year after calibration, at operating temperatures of 18 C to 28 C with relative humidity of 0% to 90%. The compact, one-handed ergonomic package makes the meter fast to deploy in the field, and the display supports both numeric readings and a bar graph for peaking and nulling adjustments. Typical applications include field service electrical troubleshooting, commercial building electrical and electronic system verification, HVAC control circuit testing, and bench verification of electronic assemblies. The 600 V CAT-rated measurement range covers most commercial and light-industrial distribution circuits. When designing a test workflow around the 115, remember that accuracy drifts after calibration; schedule annual calibration to preserve the 0.1% basic DC accuracy specification, and use the Min/Max mode rather than visual reading when capturing intermittent dropouts.
