The four test volt-ages available are 500 V, 1 kV,
2.5 kV and 5 kV. The instruments are sup-plied with a locking or
non-locking test button. The locking button allows hands-free
testing, the non-locking button is recommended to prevent accidental
misuse 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)
alka-line 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. |
