When a UK emergency lighting components
manufacturer started the search for their new
common test platform, they were faced with the
problem of hundreds of product types and an
expensive failed attempt to automate the
process in the past.
The testing required a 1,500V high voltage
flash test followed by a set of functional
routines based around mains voltages and
battery simulation. A high level of flexibility
had to be incorporated in order to cover the
hundreds of variants in both voltages and
loads.
Solution
Terotest produced the most competitive solution - iTest LT -
based around their iTest platform and designed a special low
cost cassette fixturing method that would enable the company
to produce the fixtures in-house.
This was coupled with a simple menu driven user interface
and a full set of test functions that could simply be
selected by the test engineer to design a new test for
additional products.
Result
Test times went from ~30 seconds down to 5 seconds and the
need for a trained operator was removed.
Terotest worked closely with the company for the first six
months to make sure that the first system met all
expectations, and subsequently delivered a further 3 systems.
