Technical Data
The Fluke 1550B is a digital
megohmmeter capable of testing switchgear, motors, generators and cables at up to 5000 V
dc. It can be used for a wide
range of tests: from simple spot
checks to timed tests and
breakdown tests. Measurement
storage and PC interface software make it ideal for preventive maintenance. Heavy-duty
leads, probes and alligator clips
fit in the custom carrying case,
for a rugged field testing kit.
Standard test voltages of
•
250 V, 500 V, 1000 V,
2500 V and 5000 V
Additional test voltages
•
available in 50 volt steps
from 250 to 1000 volts,
100 volt steps from 1000 to
5000 volts
