Electrical test solutions for power tool maker
May 1st 2008 ASurrey-based manufacturer
of decorating power tools
has maximised productivity
and ensured consistent quality
control across a diverse product
range following the installation of
dedicated electrical test systems.
Earlex manufactures such
products as steam wallpaper
strippers, electric spray guns and
spray stations and steam and
vacuum cleaning systems.
Clare Instruments has
developed bespoke test systems
to ensure full product testing for
electrical safety compliance as
well as various performance and
function tests. In particular, its end
of production line systems
eliminate all risk of electric shock
to the operator and reduce the
track time taken to test the product.
Customised test stations for
each product range feature
special safety enclosures that
reduce operator involvement to
the simple loading and un-loading
of products in the test fixture.
Tests are automatically applied
when the enclosure lid is closed.
For Class 1 electrical products
testers apply earth continuity, flash
(hipot) and insulation resistance to
pre-set parameters to establish
compliance with appropriate
safety standards. For Class II
products they apply a flash (hi
pot) test.
The test stations are configured
to carry out special load (watts)
tests and pressure tests to verify
the performance specifications of
the various products. For load
tests, wattage readings are
displayed on a digital meter.
Each tester has a dedicated
fault simulator that verifies that the
instrument's fault detection circuits
are working and test instruments
are checked for calibration
accuracy twice daily. More articles from Clare Instruments C/o Seaward Electronics Ltd: |
