Overview

The Fluke 87V is a high-performance industrial True-RMS multimeter designed to handle complex signals and high-energy environments. It features a unique selectable low-pass filter for accurate voltage and frequency measurements on adjustable speed motor drives and other electrically noisy equipment. With a 4.5-digit mode for precise readings and a built-in thermometer, it serves as a versatile primary tool for industrial troubleshooting.

Why Choose This Part

The unit provides CAT IV 600V safety ratings and True-RMS AC sensing for accurate measurements on non-linear signals. It offers a high-resolution 20,000 count mode and an analog bargraph for observing fast-changing or unstable signals that digital digits might miss.

Applications

Adjustable Speed Drive Troubleshooting
Utilize the selectable low-pass filter to accurately measure voltage and frequency on the output of VFDs while blocking high-frequency noise.
Industrial Control Maintenance
Monitor PLC I/O signals and control loops using the high-accuracy DC voltage and current ranges with 0.05 percent basic accuracy.
Power Quality Analysis
Identify intermittent power issues using the Peak Capture feature to detect transients as fast as 250 microseconds.
Thermal Monitoring
Use the integrated thermometer and included bead-type thermocouple to check for overheating in electrical panels and motors without carrying a second instrument.
