Instruments Model 5000N (Cat. #186.100) is a portable, multi-
range, high-sensitivity megohmmeter capable of measuring a wide range
of insulation resistances from 10 kilohms to 3000 gigohms (3,000,000
megohms). The Model 5000N has four test voltages of 500, 1000, 2500,
and 5000 volts. Each test voltage setting has two overlapping resistance
ranges of 30M
Ω
to 30,000M
Ω
and 3G
Ω
to 3000G
Ω
on a long (9.4") dial.
In addition, the Model 5000N has a unique low insulation test range of 10
to 30,000k
Ω
with a constant current of 33µA (maximum voltage of
1300V
DC
), which is useful for testing old or flooded installations. A
voltmeter (safety check) with a range of 0 to 600 volts is standard.
The Model 5000N may be powered by either AC or DC. DC power is
supplied by eight 1.5V alkaline “AA” batteries. As an option, an AC line
supply module and cord for 110/220V
AC
at 47 to 400Hz can be inserted
in the battery compartment.
An audible signal, consisting of approximately ten beeps per minute, is
present when the megohmmeter is ON, and serves as a time base for
tests of long duration. A green LED, when ON, indicates that the
batteries are good when the push-to-test button is depressed. It also
serves as a warning light when the instrument is in use, indicating that
the selected test voltage is present at the terminals.
