Fluke 1587FC Insulation Multimeter with Fluke Connect

I'm an industrial and commercial electrician. I originally purchased a 1587 as part of the 1587-MDT (Motor Drive Troubleshooting) Kit, with the 400A current clamp, thermocouple, and 9040 Phase Rotation Indicator. I often troubleshoot and commission motors, and the 1587 was my go-to DMM. It's now been replaced by the 1587FC The added features of Fluke Connect, the automated temperature correction when conducting IRT (Insulation Reisitance Tests), and automated PI (Polarization Index) and DAR (Dialectric Absorbtion Ratio) tests have simplified and streamlined my troubleshooting procedure. Documentation of troubleshooting and of pre-start motor commissioning or re-commissioning now is clear, and simple. The graph of an IRT for a borderline motor winding really helps me explain to a customer the problem, or potential problem, with a motor. And, it's saved customers money when I can document a motor's or compressor's health where other technicians have played the "it's a bad motor" card. The most innovative use I found for my 1587FC is in tuning a 0-10VDC PID (Poportional gain, Integral gain, Derivitive gain) pressure control loop. The realtime graphing function with Fluke Connect allowed me to see the resultant pressure of the VFD's response in realtime as I adjusted the P, I, and D values of the VFD. And the value of documentation is priceless.

I have been an electrician for over four years since I left high school in 2012. I have used many instruments in the past four years as a marine electrician. This is probably one of the best all-around instruments for Megging and checking continuity that I can think of. It also has so many other features such as checking temperature diodes current and voltage.
