To check the unit quickly, install any interface connectors, plug the unit into the proper
voltage and follow the steps outlined under operating instructions. If the unit does not
operate, contact the factory for instructions.
Of prime consideration and importance in the layout and installation of a test station is to
insure the safety both to the operator and any visitors or casual bystanders, invited or
otherwise. As a general rule it is suggested that each test area be in a location with
minimum distractions and not subject to extremes of temperature and moisture.
One of the more important ways to promote safety is through operator training. Benefits
of training are twofold. First, thorough training promotes safety which may significantly
reduce injuries on the job. Second, it ensures adequate testing of the product which helps
increase product reliability. Both of these can have a positive impact on profits.
An additional consideration in any test station is operator comfort. This is affected by the
operator's position, which includes the chair, table, test equipment, the object under test
and the test procedure itself. The chair and work bench or table should be nonconductive
and the table as large as possible to allow sufficient room for the test equipment and the
object under test. Studies should be made of the test requirements and work habits and
steps taken to ensure that any unusual or unnatural motion is not required and to eliminate
any repetitive motions that may produce injuries such as carpel tunnel syndrome.
After the equipment has been installed, a careful study should be made of the test station
to determine what, if any, safeguards are needed. It is suggested that any electrical test
station involving voltages in excess of 42.4 volts peak (approximately 30 volts RMS)
should be equipped with safeguards. These should operate both for the protection of the
operating personnel and for the protection of casual bystanders. At the minimum,
safeguards should prevent the operating personnel or casual bystanders from coming into
contact with the test circuit. In the event electrical interlocks of any sort are required,
either to insure that guards are in place, or to insure that the operator's hands are in a safe
location, the installer should refer to the proper schematic drawing and install these
interlocks in series with the external interlock terminals provided in the tester. All testers
may be safety interlocked with series manual or automatic safety switches, relays, etc. as
desired. In the simpler units, this is done by inserting such interlocks in the AC supply
ahead of the tester. In some units adapter plugs with remote interface controls are
provided for this purpose. We will be happy to provide suggestions and schematics for
safety interlocking our test equipment.
Any electrical power receptacle utilized to operate this equipment must be a properly
grounded three wire receptacle that has been checked for proper polarity.
The test procedure should be well thought out to ensure that it adequately tests the
product to the desired criteria but, that the procedure does not require the operator to
perform tasks that are unsafe. The product should never be touched during a test and in
