Fluke 87V True TRMS Industrial Multimeter for Industrial Application

Fluke 87V True TRMS Industrial Multimeter

The Fluke 87V True RMS Industrial Multimeter is a flagship product from Fluke, renowned for its accuracy, reliability, and robust design, making it an essential tool for industrial electricians, technicians, and engineers. It’s specifically designed to handle the complexities of industrial environments.

Features & Specifications:

• True-RMS AC Voltage and Current: This is a crucial feature for industrial applications. Special featurs of such in the Variable Frequency Drives (VFDs) output measurment and other electronic loads. Standard multimeters only measure true RMS for pure sinusoidal waveforms, leading to inaccurate readings on distorted signals.
• Low Pass Filter (LPF): A unique feature that allows for accurate voltage and frequency measurements on noisy VFDs and other electrically noisy equipment. This filters out high-frequency noise that can interfere with readings, providing stable and reliable measurements at the VFD’s input and output, and even at the motor terminals.
• High Accuracy:
  • DC Voltage: ±(0.05% + 1)
  • AC Voltage: ±(0.7% + 2) True RMS
  • DC Current: ±(0.2% + 2)
  • AC Current: ±(1.0% + 2) True RMS
• Wide Measurement Ranges:
  • Voltage (AC/DC): Up to 1000 V
  • Current (AC/DC): Up to 10 A (20 A for 30 seconds maximum)
  • Resistance: Up to 50 MΩ
  • Capacitance: Up to 9,999 µF
  • Frequency: Up to 200 kHz
  • Temperature: Built-in thermometer with 80BK K-type temperature probe included (-200 °C to 1090 °C / -328 °F to 1994 °F, excluding probe).
• Advanced Troubleshooting Features:
  • Peak Capture: Records transients (fast-changing signals) as short as 250 µs, which is vital for identifying intermittent glitches or power disturbances.
  • Min/Max/Average Recording: Automatically captures and stores the minimum, maximum, and average readings over a period, useful for monitoring signal fluctuations.
  • Relative Mode: Allows for zeroing out test lead resistance for accurate low-ohms measurements.
  • Auto and Manual Ranging: Offers flexibility in measurement.
  • Input Alert: Audible warning against incorrect test lead placement, enhancing safety.
• Safety Rating: CAT III 1000 V and CAT IV 600 V, designed to withstand impulses in excess of 8,000 V, ensuring high levels of safety for industrial environments.

Industrial Applications:

• Motor Drives (VFDs/VSDs): Its primary strength lies in accurately measuring voltage, current, and frequency on adjustable speed motor drives. This helps in diagnosing issues with the drive itself, the motor, or the cabling between them.
• Plant Automation: Essential for maintaining and troubleshooting PLC-controlled systems, sensors, actuators, and control circuits.
• Power Distribution: Identifying voltage drops, phase imbalances, current overloads, and other power quality issues in industrial power systems.
• Industrial Electronics: Troubleshooting power supplies, control boards, and other electronic components within industrial machinery.
• HVAC/R Systems: Checking motor performance, sensor readings, and control signals in industrial heating, ventilation, air conditioning, and refrigeration units.
• Temperature Monitoring: Using the built-in thermometer and probe for routine temperature checks of bearings, motors, and electrical components to identify overheating.

Why it stands out for industrial use:

The Fluke 87V’s ability to provide True-RMS measurements with a low-pass filter on noisy, non-sinusoidal waveforms found in modern industrial equipment (especially those involving VFDs) is what truly differentiates it from standard multimeters. This ensures technicians get accurate and reliable readings, taking the guesswork out of complex diagnostics
