Testing - BC Biomedical SA-2010S User Manual

TESTING

The SA-2010S Models allow 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.

TEST PROCEDURES AND MEASUREMENT LIMITS
The Analyzer requires a good Earth/Ground connection for operation. It should be
plugged into a "Hospital Grade" receptacle where available. This is necessary for both
valid test results and personal safety.
Power Receptacle Confirmation
Once plugged in, the first step is to ensure that the wall receptacle 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 only the two green lights.
NOTE: Neutral/Ground Reversal is not checked.
NOTE: These Indicators are valid only for 120 VAC Non-Isolated Power Systems.
Mains Voltage
With the Mains Voltage function selected, the display will show the Voltage that is
present on the incoming power lines. This is measured from Line to Neutral. Note that
the voltage may drop when the DUT is turned on. Ensure that this value is within the
DUT specifications.
