DESCRIPTION
The new Megger BMM500 series of
Insulation/Continuity testers provide all
the necessary features for electrical
installation testing and servicing
needs. The series incorporates the
knowledge gained from over 100 years
experience in insulation tester design.
All instruments are microprocessor
controlled
combining
performance with ease of use. For
ultimate reliability the BMM500 series
is waterproof and dustproof to IP54
and is supplied with a 3 year warranty.

Intelligent Safety System (ISS)
With increased pressure of time to
complete jobs it is inevitable that whilst
performing tests on an electrical
system mistakes will occasionally be
made exposing the user to danger or
under certain circumstances damaging
the instrument. The BMM500 series
incorporates
Megger’s
Safety System which has been
designed to ensure that such mistakes
don’t become disasters.
The ISS consists of:
Intelligent
Live Circuit Warning,
Warns of accidental connection to
a live circuit greater than 25V on
any range
Safe Contact Detector
Prevents danger during continuity
testing if contact is made with a live
circuit and minimises the chances
of blowing the instruments fuse.
Test Lockout
Prevents test being energised
in presence of external voltages.
Default Voltmeter
Displays presence of dangerous
voltages on connected circuit
irrespective of instrument range
selected.
Auto Discharge
Safely discharges connected
circuits after insulation test.
Instant Response "ZAP" Buzzer
The audible buzzer range is frequently
used for checking for correct polarity in
installed circuits and for point to point
connectivity in servicing. It is vital that
the instrument provides an instant
response in such situations. Many
insulation testers take up to 1 second
to respond making them highly tedious
and frustrating in use. The MEGGER
BMM500 series features specially
designed "instant response" circuitry
some 80 times faster than rival
products, making the instrument a
pleasure to use.
The "Zap" Buzzer also features seven
user selectable thresholds below

sen limit the buzzer will sound an inter-

This provides a useful audible
approximation of the value being
measured.
D.A.R.T. Display
The BM500 series incorporates a large
backlit digital LCD display combining
Digital
and
Analog
Technology. The patented design
provides the benefits of true analog
clarity, (with its ability to spot an
momentary insulation breakdown or
poor continuity connection), with the
stability and simplicity of a digital
reading. The display is backlit
enabling use in dimly lit areas, which is
especially useful when the installation
power is turned off for testing.

Insulation Testing
Instruments are available with either
one, two or three insulation test
voltages to suit all needs.
BM503 = 250V, 500V, 1000V
BM502 = 500V, 1000V
BM501 = 500V
Whichever model is chosen the ranges
are capable of supplying 1mA test
current at the minimum pass levels
