Built-in
microprocessor based multi range time interval meter.
Panel
with clear and easy to read legends.
Continuously
adjustable output, AC Amp. and AC volts.
Digital
ammeter and voltmeter.
Auto
cut-off and output isolated.
Portable,
suit-case model.
Self
sensing of contacts, i. e. NO / NC.
Timer
automatically puts OFF the output, when timer reaches to
its maximum value of the selected range. This ensures safety
of
the instrument as well as the item under test.
Potential-free
start and stop signal.
Wide
range of measurement, i. e. from I millisec. to 9999secs.
Application:
Protective devices such
as relays, overload coils, circuit breakers must be checked
regularly to ensure that, they are always ready to operate
correctly. If a fault occurs in the equipment, which they
are protecting, routine relay testing will quickly detect
the faulty, incorrectly adjusted protection circuit and
will possibly prevent serious damage to plant or injury
to personnel .As well as checking of the protective circuits
correctly, it is usually necessary to measure its operating
time. The microprocessor based time interval meter is used
for this purpose in all Kospi brand relay test sets.
