The Fluker 115's performance is rooted in its exceptional technical specifications, which cover all essential measurement functions required for field work. Every parameter is engineered to deliver laboratory-grade accuracy in real-world conditions, ensuring that technicians can trust their readings even in noisy, high-interference environments.
- DC Voltage Range: 0.1 mV to 1000 V, with an accuracy of ±0.09% (for readings ≥1 V). This precision ensures that even small voltage fluctuations-such as those indicating a failing component or poor connection-are detected reliably. The low-end sensitivity (0.1 mV) makes it suitable for testing delicate electronics, while the 1000 V max range handles high-voltage systems common in industrial and commercial settings.
- AC Voltage Range: 0.1 mV to 1000 V (RMS), with an accuracy of ±0.7% (for readings ≥1 V). Crucially, the Fluker 115 features true RMS measurement, a must-have for field work where non-linear loads (e.g., LED lighting, variable frequency drives, computers) produce distorted waveforms. Unlike average-responding multimeters that inaccurately measure these waveforms, true RMS ensures precise readings regardless of signal shape, eliminating guesswork when troubleshooting modern electrical systems.
- Safety Ratings: The Fluker 115 is certified to CAT III 600 V and CAT IV 300 V standards, meaning it can safely withstand transient voltages (voltage spikes) common in industrial environments, utility connections, and commercial buildings. This certification is non-negotiable for field technicians, as it protects against electrical hazards and ensures compliance with global safety regulations (e.g., IEC 61010-1, NFPA 70E).
Features
- In-Line Current (AC/DC): Ranges from 0.1 µA to 10 A, with an accuracy of ±0.2% (DC) and ±1.0% (AC). In-line measurement is ideal for direct access to circuits, such as testing fuses, breakers, or small motors. The 10 A max range covers most field applications, from low-current electronics to medium-duty industrial components.
- Clamp-On Current (Optional): The Fluker 115 is compatible with Fluker's line of i400/i400s AC current clamps (sold separately), enabling non-contact current measurement up to 400 A. This is a game-changer for field work, as it eliminates the need to disconnect wires-saving time and reducing the risk of downtime. Non-contact measurement is particularly useful for hard-to-reach circuits, live equipment, or systems where shutdowns are impractical.
- Current Protection: The multimeter features built-in overload protection for current inputs (10 A fuse for in-line measurements), preventing damage to the instrument (and the user) in case of accidental overloads-a common hazard in fast-paced field environments.
Product Overview
- Resistance Measurement: Range of 0.1 Ω to 50 MΩ, with an accuracy of ±0.1% (for readings ≥1 Ω). The wide range covers everything from low-resistance connections (e.g., wire splices) to high-resistance components (e.g., resistors in electronics). The high accuracy ensures that even subtle resistance changes-indicative of corrosion, loose connections, or component degradation-are detected.
Continuity Testing: A built-in audible beeper alerts technicians to low-resistance paths (≤50 Ω), allowing for hands-free testing. The beeper's intensity increases as resistance decreases, so technicians can focus on manipulating wires or components without constantly checking the display. This is invaluable for quickly verifying that a circuit is complete (e.g., testing a light switch or a wire run) or identifying breaks in wiring.
Diode Testing: Measures forward voltage drop (0.1 V to 2.0 V) with an accuracy of ±1.0%, enabling technicians to test diodes, LEDs, and semiconductor components. The multimeter provides a visual and audible indication of a good diode (forward bias) or a faulty one (open or shorted), simplifying the diagnosis of electronic circuits in HVAC systems, industrial controls, and consumer electronics.
Capacitance Measurement: Range of 1 nF to 1000 µF, with an accuracy of ±2.0%. Capacitors are critical components in HVAC systems, motor starters, and electronic controls, and a failing capacitor is a common cause of equipment breakdown. The Fluker 115's capacitance function allows technicians to quickly test capacitors in situ (or off the board) to verify their value, identifying weak or faulty capacitors before they cause costly downtime.
Frequency Measurement: Range of 1 Hz to 1 MHz, with an accuracy of ±0.1%. Frequency measurements are essential for troubleshooting variable frequency drives (VFDs), generators, and audio/control circuits. The Fluker 115 can measure frequency from both voltage and current inputs, making it versatile for testing different types of equipment-from a VFD's output frequency to the pulse frequency of a sensor.
Display Specifications: A large, backlit LCD screen (2.2 inches) with high contrast ensures readability in all lighting conditions-from bright sunlight (thanks to the anti-glare coating) to dark crawl spaces or equipment cabinets. The display shows up to four digits (plus a sign and decimal point) with a maximum count of 6000, providing clear, precise readings without cluttering the screen.
Auto-Ranging and Manual Ranging: The multimeter defaults to auto-ranging, which automatically selects the appropriate measurement range based on the input signal. This eliminates the need for technicians to manually switch ranges, saving time and reducing the risk of errors (e.g., selecting a range that's too low and overloading the instrument). For advanced users or specific applications, manual ranging is available via a dedicated button, allowing for more control over measurements.
Hold Function: A "Hold" button freezes the current reading on the display, so technicians can take measurements in hard-to-reach places (e.g., inside a tight electrical panel) and then read the value once they're in a comfortable position. This is particularly useful for voltage or current measurements where the test leads are difficult to position while watching the display.
Min/Max/Average Recording: The Fluker 115 can record minimum, maximum, and average values over time, which is ideal for monitoring fluctuating signals (e.g., voltage drops during motor startup or current spikes in a circuit). The multimeter updates these values in real time, allowing technicians to identify intermittent issues that might be missed with a single reading.
