TESTING

WARNING
All connections to patients must be removed
before connecting the Device Under Test (DUT)
to the Analyzer. A serious hazard may occur if
the patient is connected when testing
with the Analyzer.
Do not connect any leads from the patient
directly to the Analyzer or DUT.
The SA-2000 Family of Safety Analyzers allows the user a great deal of flexibility in testing.
Any of the basic tests can be run and in almost any sequence. The information in this
section presents a systematic approach that is just one way to proceed. It is only
presented as a guide and it is the responsibility of the user to establish which tests are
required based on local codes, facilities practices and equipment manufacturer's
recommendations.
The Analyzer requires a good Earth/Ground connection for operation. It should be plugged
into a "Hospital Grade" receptacle. This is necessary for both good test results and
personal safety.
The unit will power up with the Neutral and Ground Closed, in Forward Polarity and with the
Hot Open. It is recommended that the unit be returned to this condition when plugging and
unplugging the Device Under Test (DUT).
Power Receptacle Confirmation
Once plugged in, the first step is to insure that the wall receptacle that the Safety Analyzer
is plugged into is wired properly (120 VAC Non-Isolated Power Systems Only). There are
three neon indicators in the unit that provide this confirmation. The REV indicator is red
and the other two are green. If the two green indicators are on, the Receptacle is wired
correctly. If not, utilize the following patterns to help determine the problem. Do not
proceed with any testing until you get the two green lights.
NOTE: Neutral/Ground Reversal is not checked.
