115 Übersicht
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.

Typische Anwendungen

Field-Service Electrical Troubleshooting
The FLUKE-115 is designed for mobile technicians diagnosing electrical faults in residential, commercial, and light-industrial installations. Its 6000-count true-RMS measurement engine and 0.1 percent DC accuracy allow reliable verification of mains-voltage circuits, lighting loads, and outlet wiring under real-world non-sinusoidal conditions (LED drivers, dimmers, VFD leakage). The 550 g weight and 167 x 84 x 46 mm footprint fit a tool belt or pouch, and the CAT III 600 V safety rating covers distribution-board work. Compared to bringing a bench multimeter, the FLUKE-115 trades absolute accuracy for portability while preserving enough precision for pass/fail troubleshooting decisions.
Empfohlen
Industrial Control-Panel Diagnostics
Maintenance technicians use the FLUKE-115 to verify 24 V DC control signals, 4-20 mA loops, and 120/230 V AC supply rails inside industrial control panels. The meter's Min/Max/Average recording captures inrush events when motors start, and the continuity buzzer speeds up wiring checks. CAT III 600 V safety allows measurements on the load side of panel disconnect switches. For pure electronics work inside the panel, the FLUKE-115's 0.1 percent DC accuracy and 40 Mohm resistance range are sufficient for sensor verification and ground-bond checks. The bar graph helps visualize slowly varying signals that a numeric-only display would miss.
Empfohlen
Electronics Bench Work
For hobbyist and light-professional electronics work, the FLUKE-115 measures DC supply rails, component values, and logic-level signals with 0.1 percent DC accuracy. The 6000-count resolution gives 1 mV resolution on the 6 V range, adequate for analog-circuit debugging. Capacitance measurement supports electrolytic and ceramic capacitor checks, and the diode-test function with audible continuity speeds up PCB bring-up. While not a replacement for a 6.5-digit bench DMM, the FLUKE-115's true-RMS AC performance is competitive with bench meters costing twice as much for variable-frequency and PWM-signal measurements.
Empfohlen
Electrical-Contractor Verification
Licensed electricians use the FLUKE-115 to verify proper wiring at newly installed or repaired outlets, switches, and lighting circuits. The meter's true-RMS AC voltage measurement is critical for circuits feeding LED drivers, dimmers, and switch-mode power supplies where waveform distortion would cause averaging meters to read low. The Hold function freezes readings on hard-to-reach conductors, and the backlit LCD allows reading in dark junction boxes. Resistance and continuity modes verify ground-bond integrity and identify cable pairs in multi-conductor runs.
Empfohlen
HVAC Electrical Diagnosis
HVAC technicians measure contactor coil voltage, capacitor microfarads, and blower-motor current with the FLUKE-115, covering the electrical side of HVAC service. For flame-sensor microamp measurement or thermistor temperature, the FLUKE-116 (HVAC-specific) is the better tool. The FLUKE-115 remains useful for voltage and frequency checks on three-phase compressor supplies up to 600 V. Its Min/Max function captures compressor inrush events that a single snapshot would miss, helping diagnose motor-start failures.
Empfohlen
PV-Solar and Renewable-Energy Installation
Solar installers use the FLUKE-115 to verify DC string voltages, open-circuit voltage (Voc) of PV modules, and continuity of grounding conductors. The meter's 600 V DC range covers residential and small-commercial string voltages, and true-RMS AC measurement verifies inverter output voltage and frequency. The compact form factor fits on a rooftop ladder or in an installer's pouch. For higher-voltage commercial arrays above 600 V DC, an MC4-compatible CAT III 1000 V meter is required; the FLUKE-115 is suited for small-system work only.

Designhinweise
Insert the test leads into the correct jacks before rotating the function switch: COM (black) plus V-ohm (red) for voltage, resistance, capacitance, frequency, continuity, and diode test; COM plus 10 A or 400 mA for current. Per the Fluke 115 user manual, attempting a current measurement with leads in the V-ohm jacks blows the internal fuse (and risks arc-flash on live circuits). Always verify the rotary-switch position and jack assignment match before touching a live conductor.
The 400 mA and 10 A current inputs are individually fused; if a current measurement reads zero unexpectedly, the fuse is the first place to check. Per the Fluke 110-series service manual, fuses are user-replaceable but the meter must be opened to access them - a step most field users delegate to a service center. Never bypass a blown fuse with wire or foil, as this destroys current-shunt accuracy and eliminates overcurrent protection on the meter's burden resistor.
On non-sinusoidal AC waveforms (VFD outputs, dimmer-controlled lighting, switch-mode power supplies) the FLUKE-115's true-RMS converter gives correct readings where averaging meters read 5-30 percent low. According to the Fluke product page, the 115 specifies true-RMS AC; however, the AC bandwidth is limited (typical 1 kHz to 5 kHz depending on range), so high-frequency PWM signals may show additional attenuation. For PWM frequencies above 5 kHz, the Fluke 87V (100 kHz AC bandwidth) is recommended.
When probing densely populated electronics boards, use the Fluke TL175 silicone test leads with adjustable shroud tips instead of the standard TP4 steel tips; the shroud prevents accidental shorting between adjacent leads and IC pins. The Hold function freezes a stable reading on the display so the probe can be removed for safer inspection of the measurement point. Avoid the Auto-Hold mode when measuring fluctuating signals (motor inrush, PWM ripple) - it can lock onto a transient and report a misleading value.
Compliance-Informationen
Compliance data not present in the verified web snippets. The Fluke 115 is a finished test instrument, not a component subject to AEC-Q100. Safety rating expected to comply with IEC 61010-1 CAT III 600 V per industry-standard Fluke 110-series specifications, but explicit certificate numbers not in the verified data.
