DESCRIPTION
The MEGGER
BM80/2 Series are multi-
voltage
insulation
testers offering advanced performance,
specification
and
simplicity of use. They have insulation
test voltages from 50 V to 1000 V d.c.,
(500 V max. on BM81/2.) The
comprehensive
achieved using the latest electronic
design and technology.
and
continuity
features,
and
specification
is
The analogue/digital LCD incorporates
the benefits of electronic arc analogue
indication with unambiguous digital
readings. The analogue scale helps to
make rapid identification of insulation
condition, and to monitor variable
readings, and is complemented by the
precision and simplicity of a digital
display. All 3 instruments in the range
are identical except that the BM81/2
has a maximum test voltage of 500 V
and the BM82/2 has no continuity
range.
In compliance with BS 7671, IEC 364,
HD 384 and VDE 0413 Part 1 and 4, the
250 V, 500 V and 1000 V insulation
ranges have a 1 mA test current at the
minimum pass values specified. The
BM80/2 and BM81/2 continuity ranges
have a short circuit test current of
approximately 205 mA in order to
comply with the requirements of these
documents. Also on the continuity
ranges, is the facility to null the
resistance of the test leads.
This enables direct readings of low
resistance to be taken. A continuity
buzzer is included on the second
continuity range.
In addition to the insulation and
continuity ranges, the BM80/2 series
has a resistance range which measures
up to 100 k
on the digital scale and up
to 10 M
on the analogue scale. Due to
the low test voltage and current of this
range, it can be used to test circuits
with sensitive equipment connected,
without causing damage.
Two voltage ranges measure up to
50,0 V and 600 V a.c. or d.c.
respectively, and indicate the presence
of negative d.c. A voltage warning is
provided in these models, alerting the
user to the presence of external voltage
greater than 25 V, by displaying the
voltage level, even when measuring on
insulation and continuity ranges. The
voltage range will indicate if capacitive
charge remains after a test, and will
monitor the automatic discharge.
On all models testing is inhibited if 55 V
is detected.
Hands free operation is offered as
standard on all ranges except the
insulation ranges. Locking and non-
locking test buttons are provided with
each instrument for user selection. Use
of
the
non-locking
button
is
recommended to prevent accidental
mis-use and injury, and in cases where
continuous operation of an insulation
test is required the locking button can
be fitted. Alternatively the optional
accessory Switched Test Probe SP1 can
be used enabling remote operation of
the test button from the negative test
probe.
The BM80/2 series is rugged, and
therefore suited to tool bag treatment,
as well as having an IP54 environmental
protection
rating
product reliability in wet and dusty
conditions. Exceptional battery life is
provided by six cells housed in
separate battery compartment.
which
ensures
The instruments are designed to IEC
1010-1, VDE0411 and BS4743 safety
standards.
