Electrical safety
All inputs are protected to the 2nd edition of ANSI/ISA S82.01 and EN61010-1 CAT IV 600V and CAT III, 1000 V. They can withstand impulses in excess of 8.000 V and reduce risks related to surges and spikes.

Correctly measure pulse-width modulated motor drive signals
Until now, there hasn't been a multimeter able to accurately measure adjustable speed drives. But the new Fluke 87V is designed specifically to handle these complex signals. Think of the potential productivity you'll gain by taking the guesswork out of drive system troubleshooting. Measurements are correct each and every time.

Unique function for accurate measurements of noisy pulse-width modulated AC voltage. Measures correctly at the ASD and at the motor terminals Accurately measure the frequency (motor speed). Frequency measurement not affected by the ASDs carrier frequency Measure AC current with an optional current clamp accessory Compare reading from the 87V with the display on the ASD Special shielding blocks high frequency, high-energy noise generated by large drive systems

Complex PWM drive signals are not a problem for the Fluke 87V
