The Fluke 1587 insulation mulitmeter combines features of an insulation tester and digital multimeter into a portable tool for electricians and technicians.
Fluke Corp., Everett, Wash., offers a multimeter that combines two frequently used, bulky testing tools into one compact tool. Fluke's 1587 and 1577 insulation multimeters include 1-kV digital insulation testers with true-rms digital multimeters that electricians and technicians carry easily into the field for troubleshooting and preventative maintenance on motors, cables, and switchgear.
According to Fluke, the 1578 version provides insulation resistance testing up to 2 G O with five output voltages from 50 to 1,000 V. In addition, the 1587 accurately measures voltage and frequency on variable-frequency motor-drive systems through a low pass filter. The 1577 tester performs up to 600 M O of resistance with 500 or 1,000 V.
