117 - Electrician's Multimeter with Non-Contact Voltage | Fluke
The Fluke 117 is a compact True-RMS digital multimeter engineered for commercial electricians working in low-light, high-interference environments such as hospitals, schools, and commercial buildings. It integrates non-contact voltage (VoltAlert) detection to identify live conductors without probe contact, a backlit LED display for dim panels, and a low-impedance (LoZ) mode that suppresses ghost voltages from capacitive coupling on long cable runs. The 117 is part of Fluke's 11x series of compact handheld DMMs and is rated for 600 V CAT III / 600 V CAT IV installation categories, allowing direct measurement at distribution panels and service entrances. A digital multimeter (DMM) is a portable electronic test instrument that combines several measurement functions—DC voltage, AC voltage, current, resistance, capacitance, frequency, continuity, and diode test—in a single battery-powered unit. Modern handheld DMMs such as the Fluke 117 are positioned in the broader test and measurement hierarchy: DMM -> portable test instrument -> electrical tester -> general-purpose test equipment. The category traces its roots to analog moving-coil meters and has evolved through successive generations of True-RMS converters, autoranging firmware, and ruggedized enclosures to become the universal diagnostic tool for electricians, HVAC technicians, and field-service engineers. The 117 measures up to 600 V AC/DC, 10 A AC/DC current via the 10 A fused input, capacitance to 1000 microfarads, frequency to 50 kHz, and resistance to 40 megohms. True-RMS acquisition provides accurate readings on non-linear loads such as variable-frequency drives, switching power supplies, and LED lighting. Auto and manual ranging, min/max/average recording, and a Hold function support trend capture during transient events. The 6000-count display gives 0.09% basic DC accuracy, sufficient for verifying control voltages and appliance calibration. Integration of VoltAlert non-contact detection eliminates a separate voltage tester; the LED at the meter tip glows red when an AC field is sensed, allowing one-hand checking of de-energized circuits. LoZ mode places a low-impedance load across the test points to drain ghost voltages that can false-trigger standard high-impedance meters on long runs—critical for HVAC and building-automation diagnostics. The combination of CAT III 600 V rating and TL175 silicone-insulated test leads permits direct measurement at building distribution panels in compliance with IEC 61010-1 and NFPA 70E standards. Typical applications include commercial building electrical troubleshooting, HVAC service diagnostics, lighting-retrofit verification, and residential service-panel testing. The 117 excels where ghost-voltage rejection and quick live-conductor detection reduce diagnostic time on commercial sites with mixed old/new wiring topologies. Field engineers pairing it with the Fluke 323 clamp meter can form the Fluke 117/323 electrician's combo kit, providing both contact and non-contact current measurement without a second tool purchase. When selecting measurement tooling, confirm installed-environment category rating (CAT III/CAT IV) matches the upstream fault current available. Always use fused test leads and inspect the meter housing for cracks before energizing; a damaged CAT III-rated meter loses its overvoltage rating and should be removed from service. Battery replacement uses a 9 V alkaline cell accessible via the rear battery door.

FLUKE-115 - True RMS Handheld Digital Multimeter, 6000 Count
The Fluke FLUKE-115 is a true-RMS handheld digital multimeter (DMM) with 6000-count resolution, designed for electrical and electronic test in field service, industrial, and commercial applications. It measures AC/DC voltage and current, resistance, capacitance, frequency, continuity, and diode forward voltage, and provides a bar-graph display for trend monitoring. The meter includes Min/Max/Average recording, a Hold function, sleep mode for battery conservation, and a backlit LCD for low-illumination work. A handheld digital multimeter is a portable battery-powered measurement instrument that combines the functions of a voltmeter, ammeter, and ohmmeter into a single tool for diagnostic and troubleshooting tasks. True-RMS (Root Mean Square) measurement is the ability to accurately read the equivalent heating value of non-sinusoidal AC waveforms such as those produced by variable-frequency drives, switching power supplies, fluorescent lighting ballasts, and computers, where average-responding meters can read up to 40% low. The 6000-count display means the meter resolves 6000 discrete steps on its lowest DCV range (e.g., 0.1 mV resolution on the 6.000 V range), providing enough resolution to debug low-voltage analog and digital circuits in the field. Key features of the FLUKE-115 include a 0.1% basic DC accuracy, a voltage measurement range from 600 mV to 600 V, a resistance range from 0.1 ohm to 40 Mohm, capacitance measurement, frequency measurement to 50 kHz, continuity with audible beep, diode test, and Min/Max/Average elapsed-time recording. The rugged overmolded case is rated to IEC 61010-1 CAT III 600 V and CAT II 1000 V for safety on distribution panels and three-phase equipment, and the unit weighs approximately 550 g with dimensions of 167 x 84 x 46 mm. The instrument uses a custom Fluke ASIC combined with a precision shunt resistor network and a delta-sigma ADC to achieve its accuracy and stability across the operating temperature band. Auto-range logic and a separate digital/analog bar graph allow fast nulling and trend observation during commissioning and commissioning-style troubleshooting of control panels, motor drives, and process instrumentation. Typical applications include field-service troubleshooting of HVAC systems and electrical panels, commercial electrician work on 120/240/480 V distribution, industrial maintenance of 4-120 mA control loops and 24 VDC sensor supplies, electronics bench work on 3.3/12/24 VDC rails, and automotive electrical diagnostics on 12 V and 24 V vehicle systems. The 600 V CAT III rating specifically covers three-phase industrial distribution panels. When selecting a multimeter, match the safety category to the highest energy source you intend to measure. The 115's CAT III 600 V rating makes it appropriate for fixed-installation industrial panels, but a CAT IV 600 V meter such as the Fluke 117 is required when measuring outdoor service entrances, overhead lines, or the supply side of the utility meter.

FLUKE-115 True RMS Handheld Digital Multimeter | Fluke
The Fluke FLUKE-115 is a true-RMS handheld digital multimeter designed for electrical and electronic field-service testing, delivering 6000-count resolution on a 3.75-digit LCD with an integrated bar graph. It measures AC/DC voltage from 600 mV to 600 V, AC/DC current, resistance from 0.1 ohm to 40 Mohm, capacitance, frequency, and continuity, and provides diode test plus Min/Max/Average recording of signal fluctuations. According to the Fluke product page, the FLUKE-115 targets field-service technicians and industrial users who need more than basic multimeter functions in a compact 167 x 84 x 46 mm, 550 g form factor. A handheld digital multimeter (DMM) is a portable bench-instrument equivalent used to measure multiple electrical quantities with one device. The category sits within general-purpose electrical test & measurement, encompassing multimeters, clamp meters, insulation testers, and oscilloscopes. The FLUKE-115 is a true-RMS meter, meaning it accurately measures non-sinusoidal AC waveforms (such as variable-frequency drives, LED lighting, and computer power supplies) where averaging meters would read low. Within Fluke's handheld DMM lineup, it sits between the entry-level 117 and the industrial 116, optimized for general electrical and electronic troubleshooting rather than HVAC or process calibration. Key features include 0.1 percent DC accuracy, a large white-LED backlit display for dim environments, a Hold function to freeze readings, and a Sleep mode to conserve battery life. The bar graph allows trend observation in the same way an analog needle would, useful when adjusting a potentiometer or watching a slowly varying signal. Safety is rated to IEC 61010-1 CAT III 600 V, allowing measurements on distribution boards, fixed industrial equipment, and three-phase motor controls. The meter's input architecture uses separate fused current jacks (typically 10 A and 400 mA) and shared voltage/resistance/capacitance jacks, with auto-ranging that selects the optimal measurement range automatically. The Min/Max/Average function records signal fluctuations over time, enabling capture of inrush currents or intermittent dropouts without continuous observation. Typical applications include field-service troubleshooting of electrical installations, industrial control-panel diagnostics, electronics-bench work, and electrical-contractor verification of mains-voltage circuits. The compact form factor and rugged overmolded boot suit mobile technicians who move between job sites daily. When designing a measurement workflow around the FLUKE-115, consider that the fused current inputs require replacement if a measurement exceeds the rating, and the Sleep mode reduces battery drain but must be disabled for long logging sessions. Use properly rated test leads (CAT III 600 V or higher) to maintain the meter's safety rating.

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.
