BULLETIN-1BM15 & MJ15 5/98 The
BM15 & MJ15 are compact 5 kV insulation testers. They are
very simple to use and provide a quick and accurate reading of
insulation resistance. The instruments use an analog display with
a maximum reading of 20 G.
A voltage range of four test voltages enables measurement of
ac or dc conductor potential. The four test voltages available
are 500 V, 1 kV, 2.5 kV and 5 kV. The instruments are supplied
with a locking or non-locking test button. The locking button
allows hands-free testing, the non-locking button is recommended
to prevent accidental mis-use and injury.
A bezel allows a scale plate overlay to be added with PASS/FAIL
bands for GO/NOGO testing. This is particularly useful for less
experienced users and enables a rapid decision to be made. The
new instruments have a choice of power source, eight x LR6 (AA)
alkaline cells or the MJ15 offers an additional hand cranked generator.
If the test button is pressed the MJ15 uses battery power. Otherwise
the crank handle is turned to save battery power or for use when
the batteries are unavailable. Both units are built into a rugged
case designed for outdoor use. The instruments are also supplied
with a soft carrying case, a test lead set, test
record cards and batteries.
Safety terminals suitable for locking connectors are used for
connection to the test piece. An automatic discharge circuit eliminates
the voltage on capacitive loads after a test. The decaying voltage
can also be viewed on the scale. Fused test leads are available
as an option for voltage measurement. The instruments meet the
IEC1010 safety specification and EMC specifications and are fully
CE marked.
