Megohmmeter Model 1000N/1100N
'HV.ULSWLRQ
®
The AEMC Model 1000N (Cat. #185.100) is a portable, multi-range,
high-sensitivity megohmmeter capable of measuring a wide range of
insulation resistances from 1 kilohm to 1000 gigohms. The Model 1000N
has five test voltages of 50, 100, 250, 500 and 1000V. Each test voltage
setting has two resistance ranges: 1 to 1000MΩ and 1 to 1000GΩ.
In addition, the Model 1000N has a unique low insulation test range of 1
to 1000kΩ with a constant current of 1mA (maximum voltage of
), which is useful for testing old or flooded installations. A
1200V
DC
voltmeter (safety check) with a range of 0 to 600V is standard.
The Model 1000N 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 at 47 to 400Hz can be inserted
AC
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.
