Fluke 1587 User manual

Technical Data
The Fluke 1587 and 1577 Insulation
Multimeters combine a digital
insulation tester with a full-featured,
true-rms digital multimeter in a
single compact, handheld unit,
which provides maximum versatility
for both troubleshooting and
preventative maintenance.
Like other tools that you have
come to expect from Fluke, the
1587 and 1577 are rugged, reliable,
and easy to use.
Whether you work on motors,
generators, cables, or switch-gear,
the Fluke 1587/1577 Insulation
Multimeters are ideally suited to
help you with your tasks.
