Description

Congratulations on your purchase of a genuine
Megger insulation/continuity tester. Megger has
over 100 years experience in insulation testing
which is reflected in its product designs. Your
BMM500 has been carefully developed to
address the real needs and benefits of the user.
The Megger BMM500 Series instruments are
battery powered Insulation and Continuity
testers, with a measurement capability from
0,01Ω Continuity to 10GΩ Insulation.
O ffering multi-voltage facilities, the instruments
take full advantage of microprocessor t e c h n o l o g y
and feature a large liquid crystal display
combining digital and analogue readings. T h e
analogue display has the benefit of indicating
trends and fluctuations in readings, while the
digital readout gives direct accurate results. T h e
display is also backlit giving clear visibility even
in low light conditions.
The BMM500 Series instruments have the
unique capability of being able to measure
voltages down to a resolution of 0,1mV. This
gives the user the option to fit a wide variety of
transducers to further enhance the capabilities
of the BMM Series instruments, eg temperature
or humidity measurement.
A customised connector on the top of the
instrument enables the optional Megger SP1
Switched Probe to be used for two handed
probe operation.
The 250V, 500V and 1000V ranges can be
used to test electrical installations in compliance
with BS7671 (16th Edition IEE
Regulations) IEC364 and HD384, since each
range has a 1mA minimum test current at the
minimum pass values of insulation specified in
these documents. Designed to IEC1010-1 the
BMM500 Series are protected
connection to a 300V Category III supply. T h e
instruments have a basic accuracy of ±2% at
20°C. The instruments are waterproof and
dustproof to IP54. This helps maintain accuracy
and ensures maximum reliability in harsh
