Fluke 87 DMM vs Fluke 88 Automotive DMM

[scott.john.mockry@bangate1.TEK.COM]

Someone asked what the difference was between the Fluke 87
and the Fluke 88 DMM's. The Fluke 87 was designed for 
electrical/electronic troubleshooting and the 88 was 
designed to accomodate automotive measurements
and it comes with a inductive RPM pickup, additional
test leads and clips and hard  plastic carrying case.

Here is what I know...... 
Apparently General Motors liked the Fluke 87 because 
of its better accuracy, 1ms pulse capture, high impedance 
mode (nano-siemans) for checking Ignition coil leakage, 
and it had a lower price than the Fluke 88.
