Megohmmeter Models 5000N/5100/5110

Description

AEMC® Instruments Model 5000N (Cat. #186.100) is a portable, multi­range, 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 30MΩ to 30,000MΩ and 3GΩ to 3000GΩ on a long (9.4") dial.

In addition, the Model 5000N has a unique low insulation test range of 10
to 30,000kΩ with a constant current of 33µA (maximum voltage of

DC), which is useful for testing old or flooded installations. A

1300V
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
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.

AC at 47 to 400Hz can be inserted

screws on the four corners of
the battery pack and remove
the battery pack.

• Replace the batteries,
observing the proper
polarities.

• Replace the battery case,
taking care not to pinch the
connecting wire, and tighten
the four screws.

AC Supply Module

The optional AC supply module (Cat. #100.142) provides power to the
Model 5000N at 110 or 220V
designed to plug into the back portion of the instrument, directly
replacing the batteries. The module is protected by a 0.1A slow-blow
fuse.

Note: Cat. #100.142 is supplied with 110V US plug.

• Unscrew the four screws on the corners of the back panel battery
pack.

• Disconnect and remove the battery pack.

• Connect the AC supply module to the power supply connector.

• Place the AC supply module into the back of the instrument and

tighten the four corner screws, making sure not to pinch the wires of
the power supply connector.

• With the tip of a screwdriver, select the proper voltage with the
110/220 supply switch on the back panel of the AC supply module

• Plug the AC supply cord into the appropriate voltage receptacle.
