How would you test a vehicle spark plug for insulation resistance using this meter? can this tool be used to test a spark plug on an automotive / aviation engine?
That application is not indicated in the user manual, but there are various methods indicated online. Here is a link to the manual for the Fluke-1587 FC: https://dam-assets.fluke.com/s3fs-public/15x7____umeng0400.pdf?5YioMR08PGjo48UkLPzmKecc1G.M0vVH

what is the recommended time interval to recalibrate the Fluke 1587 FC?
Fluke recommends yearly calibration for those customers that are subject to audits. The certificate is dated for a one year expiration. Otherwise, an every other year cycle is recommended.

What are the recommended batteries to use
is there a separate part number for the 1587-FC with calibration certificates?

Rated 5 out of 5 by Austin from Fluke Connect made a great instrument better. I just recently upgraded to this new 1587FC, but the 1587 has always been my go to favorite insulation tester. The fluke connect feature, while not something I use extremely regularly, does work amazingly when you need it. It is very convenient to be able to see your meter readings from your phone even if you're not close to the meter itaelf.

Rated 5 out of 5 by Korey from Best Multi-Meter/Megger Combo 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.

Rated 5 out of 5 by Derk from AWESOME COMPACT METER WITH BIG CAPABILITIES! Saw a coworker breakout his 1587 Fluke to do what i have only seen done in motor shops... I was sold. I looked and found the Fluke 1587FC for a great price. Have used this on my own now several times in place of guessing with my other more basic fluke meter, Takes the guesswork out of trouble shooting and adding a great deal of customer confidence! This meter has been a huge time saver making a better bottom line. no longer performing further repairs on motors only to find deeper problems! (Quicker repairs) I would definitely purchase this meter again! Highly recommended. Derk G. Utah

Rated 5 out of 5 by GTB02 from Two meters in one As a defense contractor working on Navy ships I use the 1587 FC Insulation Multimeter daily. We are required to perform insulation resistance checks using 500 volts as well as continuity checks. This meter can accomplish both. No need to carry two meters around. The remote probe and ability to record data on my phone is a real time saver and ensures accuracy. The display has large digits that are easy to read in dark locations. The meter can be used with the FLUKE SV225 Stray Voltage Eliminator to prevent false reading from ghost voltage. Very versatile meter.
