This section looks at a SA-2000 layout and gives descriptions of the elements that are
present.
The user controls all Analyzer functions via 6 light touch keys. There is an audioclickwhen
any key is depressed, while a “Razz” or error tone consisting of a rapid succession of
beeps is sounded if an invalid key is depressed. There are 13 LEDs to provide the user
with full information about the test that is being performed and the current setup. A 3-1/2
digit LCD display conveys DUT test results to the user. The following is a review of the
layout and operation of each of the elements.

SA-2000-INTL Layout SA-2000-AUS Layout
The SA-2000-INTL and SA-2000-AUS Model Layouts are shown above, note that the
only differences from the standard model are the Line cords and the DUT test
Receptacles.
Note: The RS-232 connector isn’t shown above for these two models, but is an available
option for both (see previous section).
Display
The main information in the system is presented in the 3-1/2 digitLCDdisplay. Thisdatais
provided as simple meter readings withthe measurementunitsindicated to theright byone
of the two LEDs.
Function Selection
Three LEDs and two keys make up the Function Selection Section. The keys are up and
down arrows. When depressed, they step the Analyzer throughtheavailableoptions. The
LED next to the currently selected option is illuminated.

5
Analyzer Test Receptacle Control
There are four keys and 8 LEDs in the Analyzer Test Receptacle Control Section. They
allow the manual control of the power connections that are made to the DUT. Internally, a
series of relays are switched by the microprocessor based on the keys that aredepressed.
The LEDs indicate the current state of the power connections to the Receptacle.
Note: The Forward/Reverse Polarity key hasa safety delay feature, preventing damage to
the internal relays and the DUT. When the key is depressed, the DUT power is disabled
and the safety delay is activated. When this delay is complete, the internal relays switch
the polarity to the DUT and apply power. This delay allows any reactive power stored in
the DUT to self-discharge before the polarity is reversed.
Note: 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 DUT.
Connectors
There is a connector for the Chassis test lead. There is a release pin on the lead plug that
must be depressed to remove the lead.
Fuse
There is a fuse in the ground leg of the Analyzer Test Receptacle. This is to help prevent
damage from excess ground current. It is located on the face for ease of replacement.
Test Receptacle
This receptacle is for the connection of the DUT. The Receptacle Rating depends on the
specific Analyzer model. SA-2000 models use a Hospital Grade North American/USA
standard NEMA 5-20R receptacle rated 20 Amps @ 125 VAC. SA-2000-INTLmodelsuse
a universal international receptaclerated 20Amps@ 250VAC. SA-2000-AUSmodelsuse
an Australian-specific AU1-10R receptacle rated 10 Amps @ 240 VAC. An externalpatch
cord may be necessary to connect devices utilizingdifferent types of plugs to the Analyzer
receptacle.
Power Cord
The Power Cord, which is connected internally, providespowertoboththe SafetyAnalyzer
and the DUT through the Test Receptacle. The Power Cord varies depending on the
Analyzer model. SA-2000 models use a NEMA 5-15P plug designed to plug into a NEMA
5-15Ror5-20R Receptacle. SA-2000-INTL models have a short IEC C20 plug forwhicha
country-specific adapter cable must be connected –See the following section for this
information. SA-2000-AUS models useanAustralianAU1-10Pplugintendedforoperation
with Australian and New Zealand AU1-10R Receptacles.

6
Communications (Optional)
On Analyzer models with the –R option, a DB-9 RS-232 Communications port is provided
to interface the analyzer with a PC. Data from the Analyzer display may be transferred
overthiscommunications linkaswellasfullcontroloverallanalyzerfunctionsandsettings.

The Model SA-2000 allows the user a great deal of flexibility in testing. Several basic tests
can be run, and in almost any sequence. The information in this section presents a
systematic approach that is just one wayto proceed. It is only presented as aguide and it
is the responsibility of the user to establish which tests are required.
The Analyzer requires a good Earth/Ground connectionforoperation. Itshouldbeplugged
into a “Hospital Grade” receptacle where available. This is necessary for both good test
results and personal safety.
Earth Resistance
With the Earth Resistance function selected, the display willshow the resistance between
the Chassis Test lead and Receptacle Earth/Ground. This resistance is a combination of
the resistance within the DUT enclosure and the resistance in the Earth/Ground Lead in
the DUT power cord.
NOTE: This test has no meaning for equipment that does not use a grounded cord.
The test requires that the Chassis Test lead be plugged into the Chassis Connector. The
other end should be connected to a solid ground point on the DUT.
The display is in hundredths of Ωand will read to 19.99 Ω. Overrange shows as “1_ _ _”.
Earth/Ground Leakage Current
With the Earth/Ground function selected and the Ground-Open, the display will show the
leakage current in the ground wire of the DUT. The displayis in µAmps and willread from
0 to 1999.
NOTE: This test has no meaning for equipment that does not use a grounded cord.
Selecting thisfunctionautomaticallyopenstheconnectiontoEarth/Groundandpassesany
leakage current through the 1000 Ω load with AAMI ES1-1993 frequency compensation.

NOTICE –PERFORMING TESTS
REFER TO DUT MANUFACTURER’S SERVICE MANUAL FOR
TEST PROCEDURES AND MEASUREMENT LIMITS.

8
Enclosure Leakage
With the Enclosure function selected, the display will show the leakage current between
the Enclosure (Chassis) and Earth/Ground. The display is in µAmps and will read from 0
to 1999.
The test requires that the Chassis Test lead be plugged into the Chassis Connector. The
other end should be connected to a solid ground point on the DUT.
NOTE: If a non-conductive enclosure is used, a 200 cm2conductive foil pad should be
used. This foil is to be placed in close contact with the enclosure and connected to the
Chassis Test lead.
Any leakage current will flow through the Chassis Test lead and then through the 1000 Ω
load with AAMI ES1-1993 frequency compensation.

9
The communication protocol provides a means to completely configure and use the
Analyzer from a PC or other device with RS-232 communications interface. This
provides for hands free or automated operation of the equipment.
Communication Port
The Serial port is configured as 115,200 Baud Rate, 8 Data Bits, 1 Stop Bit, and No
Parity.
Command Syntax
The command description is broken into columns; the KEYWORD, the NODE and the
VALUE.
The KEYWORD provides the name of the command. The actual name of the command
consists of one or more keywords since SCPI commands are based on a hierarchical
structure, also known as a tree system.
In such a system, associated commands are grouped together under a common node in
the hierarchy, analogous to the way leaves at a same level are connected at a common
branch. This and similar branches are connected to fewer and thicker branches, until they
meet at the root of the tree. The closer to the root, the higher a node is considered in the
hierarchy. To activate a particular command, the full path to it must be specified.
This path is represented in the followingtables by placing the highest node in the left-most
position. Further nodes are indented one position to the right, below the parent node.
The highest level node of a command is called the Keyword, followed by the Node, and
then the value.
Some commands allow for reading and writing data and some commands are Read Only.
To indicate a read function, a question mark (?) is placed at the end of the command path.
For example, to change the mode to Earth Resistance measurement, “CONFigure:MODE
ERESistance<cr>”, where <cr> indicates a carriage-return. To read the current operating
mode of the device, a mode read command would be “CONFigure:MODE?<cr>”, which
would return the current operating mode of the device.
Lowercase letters indicate the long-form of the command (for example,
CONFigure:MODE ECGwaveforms) and can be omitted for simplification. Uppercase
letters indicate the abbreviated, or short-form,ofthecommandsandmustbeincluded(for
example, CONF:MODE ECG).
All commands sent to the unit are terminated with a Carriage Return.
NOTE: Commands can be entered in either upper or lowercase or a mixture of the two,
uppercase and lowercase. Commands sent to the device are not case sensitive. Upper
