Fluke 88V/A Automotive Meter Combo Kit Fluke 78 Automotive Meter

The right meters for auto-electric diagnosis

Perhaps the most important tool you'll use	duty cycle, make diode tests, and
in troubleshooting auto electrical systems	measure temperature, pressure and
is the multimeter. Basic multimeters	vacuum.
measure voltage, current and resistance,
while automotive multimeters like the
Fluke 78 or Fluke 88V have features that
can check things such as frequency,
