Megohmmeter Models 5000N/5100/5110
Description
®
AEMC
Models 5100/5110 are portable, multi-range, high-sensitivity
megohmmeters capable of measuring a wide range of insulation
resistances from 10 kilohms to 3000 gigohms. The Model 5100 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 (3,000,000MΩ). The Model 5110 features a color
display and also has test voltages of 500, 1000, 2500, and 5000 volts.
Each test voltage setting has two overlapping resistance ranges of 3MΩ
to 3000MΩ and 3GΩ to 3000GΩ (3,000,000MΩ).
The Models 5100 and 5110 have a unique low insulation test range of 10
to 30,000kΩ with a constant current of 33µA (maximum voltage of
), which is useful for testing old or flooded installations. A
1300V
DC
voltmeter (safety check) with a range of 0 to 600 volts is standard.
Both models feature a digital clock timer that indicates time and date.
The timer allows accurate testing on time-based test applications. The
timer may be programmed in one of two modes: to indicate the elapsed
time of applied test voltage, or the time elapsed since the test voltage
has been stopped (discharge time).
An audible signal consisting of approximately ten beeps per minute is
present when the test voltage has been applied, and also serves as a
time base for tests of long duration.
The Models 5100/5110 may be powered by either AC or DC. DC power
is supplied by a 12V rechargeable nickel-cadmium battery. AC supply
voltage may be either 110V or 220V via the removable line cord, which
plugs directly into the front of the instrument. Neon lamps on the front
panel indicate battery status; a green light indicates battery charge/AC
supply, while a red light indicates the battery charge status.
The rugged field case in safety yellow is weatherproof and rainproof
when closed. The instrument cover is also removable. The Models
5100/5110 are specifically designed for field, utility, and industrial use.
