CAUTION
The Analyzer is not a continuous duty device.
Do not leave the device under test (DUT)
connected to this unit for extended periods. It is
intended for short duration testing within the
current limits and duty cycles specified.
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.
WARNING
The Analyzer applies 120 or 240 VAC plus 10% to
the Patient leads or External test leads during
the Isolation test. Although this is current
limited by a 121K ohm internal resistor, per
standard test specifications, care should be
taken to prevent contact with this voltage.
Do not touch the test leads, connections or DUT
while depressing the Isolation Test key.

The basic layouts of the three models are the same, with variations occurring with hardware
that is not used in all the models. This section looks at a SA-2010 and is followed by
pictures of the SA-2005 and SA-2001, with the elements that are present in those models
labeled.
The unit is controlled by 10 light touch keys. They allow the user to perform all the
functions available in the system. There is an audio click when a key is depressed. Note
that some keys are locked out based on the current function setting. If an invalid key is
depressed, a Razz tone is sounded.
There are 34 LEDs and 3 Neon indicators to provide the user with full information about
the test that is being performed and the current setup. This section will review the layout
and operation of each of the elements.

Display
The main information in the system is presented in the 3½ digit LCD display. This data is
provided as simple meter readings with the units indicated by one of the four LEDs on the
right of the display. The units LEDs will automatically change to the necessary range
based on the function selected.
Function Selection
Nine LEDs and two keys make up the Function Selection Section. The keys are up and
down arrows. When depressed, they step the Analyzer through the available options. The
LED next to the currently selected option is illuminated.
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 are depressed.
The LEDs indicate the current state of the power connections to the Receptacle.
Note: The Forward/Reverse keys have an internal switching delay feature that first turns off
the power to the DUT, delays for a short period, reverses the lines and the turns the unit
back on. This eliminates the need for the user to remember to delay at this point or risk
damage to the Analyzer.
Load Selection
The unit may either use the AAMI ES1-1993 or IEC 601 Test load for measurements. This
is selected by the Load key and the current Load selection is indicated by the LEDs.
Patient Lead Control
In the maximum configuration, there are ten patient lead inputs. During testing, it is
necessary to select between these leads, select all of them and apply High Voltage to
them. This section provides the control keys to do these test configurations and the LEDs
to indicate the current state.
There is one LED for each input. Internally, there is a relay for each lead. The LEDs
indicate when that relay is on, thus selecting the indicated lead. The left and right arrow
keys sequentially select each lead in order and scroll through from None to 1-10 to All and
around again.
To apply High Voltage to the leads, the Isolation Test key is depressed. It is only active in
the Isolation mode. It is a momentary key, the voltage is only applied while the key is held
down.

Power Outlet Indicators
These three Neon indicators help verify the polarity and wiring of the wall Receptacle that
the Safety Analyzer is plugged into.
Connectors
There are two connectors for test cables on the unit. One is for the Chassis lead and the
other is for one of two different leads used for external testing. The test cables simply plug
into the sockets. There is a release pin on the cable plug that must be depressed to
remove the cable.
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.
Patient Lead Connectors
The universal patient lead connectors are located on the face of the unit for ease of
connection. They accept both standard snap and banana jack connectors. The spring
loaded ball construction insures a good connection for the various sizes of banana jacks.
Test Receptacle
This receptacle is for the connection of the Device Under Test (DUT). It is Hospital Grade,
rated 20 A. An external patch cord is necessary to connect devices utilizing different types
of plugs.
Power Cord
The unit uses a standard Hospital Grade power cord. This cord provides power to both the
Safety Analyzer and the DUT. The connector is designed to plug into a 15A, 125 VAC,
Receptacle. For higher voltage and current applications, an external patch cord is required.
Self Test Points
There are two test points on the side of the unit that allow for a quick self test of the
Analyzer. They provide a fixed 1.0 Ohm resistance to Earth/Ground and a 100 µAmp
source to Earth/Ground.

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.
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.

10
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. Insure that this value
is within the specifications for the equipment that is to be tested. Also note that the voltage
may drop when the DUT is turned on. It is the value with the DUT powered that must be
within the DUT specification.
Device Current
With the Device Current function selected, the display will show the current draw of the
DUT. This is measured in hundredths of an Amp up to 19.99 Amps. The Receptacle
should be configure with Hot-Closed, Neutral-Closed, Ground-Closed and Polarity-Fwd, for
this measurement.
Earth Resistance
With the Earth Resistance function selected, the display will show the resistance between
the Chassis Test lead and the Earth/Ground Pin on the Analyzer Test Receptacle. 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 three-wire
(Earth/Grounded) power cord.
The test requires that the Black (Kelvin) test cable be plugged into the Chassis Socket. The
other end should be connected to a solid ground point on the DUT. Consult the equipment
manufacturer’s documentation for the recommended connection point.
Since the Black (Kelvin) cable removes any error from the test lead and the internal
circuitry uses a similar connection at the Analyzer Test Receptacle ground pin (providing a
true 4 wire reading), the value displayed is the actual resistance of interest, without any
compensation. The display is in hundredths of Ohms and will read to 19.99 Ohms.
Overrange shows as 1_ _ _.

11
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 display is in µAmps and will read from
0 to 1999.
Selecting this function automatically opens the connection to Earth/Ground and passes any
leakage current through a 1000 Ohms load with either AAMI ES1-1993 or IEC 601
frequency compensation as selected by the Load key.
The test should be performed for all receptacle switch combinations as called out in the
Test Matrix, or a subset of these based on the manufacturer’s specifications or local codes
and protocols.
NOTE: This test has no meaning for equipment that does not use a three-wire
(Earth/Grounded) power cord.
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 Black (Kelvin) test cable be plugged into the Chassis Socket. The
other end should be connected to a solid ground point on the DUT. Consult the equipment
manufacturer’s documentation for the recommended connection point.
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
Black lead.
Any leakage current will flow through the Black lead and then through a 1000 Ohms load
with either AAMI ES1-1993 or IEC 601 frequency compensation as selected by the Load
key.
The test should be performed for all receptacle switch combinations as called out in the
Test Matrix, or a subset of these based on local codes, facilities practices and equipment
manufacturers recommendations.

12
Lead to Earth/Ground Leakage
With the Lead to Earth/Ground function selected, the display will show the leakage current
between the selected Patient Lead and Earth/Ground. The display is in µAmps and will
read from 0 to 1999.
Attach the patient leads to the connectors on the top of the Safety Analyzer. The left and
right arrow keys may then be used to select any individual lead or all of the leads.
Internally, relays connect the leads as necessary. The LEDs indicate the selected lead(s).
The test should be performed for all receptacle switch combinations as called out in the
Test Matrix, or a subset of these based on local codes, facilities practices and equipment
manufacturer’s recommendations. This is to be done for each lead individually and all leads
together.
This test measures the leakage current that would flow through the leads if the patient were
to come into contact with Earth/Ground.
Lead to Lead Leakage
With the Lead to Lead function selected, the display will show the leakage current between
the selected Patient Lead and All other patient leads. The display is in µAmps and will read
from 0 to 1999.
Attach the patient leads to the connectors on the top of the Safety Analyzer. The left and
right arrow keys may then be used to select any individual lead. Internally, relays connect
the leads as necessary. The LEDs indicate the selected lead.
The test should be performed for all receptacle switch combinations as called out in the
Test Matrix, or a subset of these based on local codes, facilities practices and equipment
manufacturers recommendations. This is to be done for each lead individually.
This test measures the current that would flow from a lead to other leads. Normally these
are Auxiliary currents from bias, measurement and sensing circuits.

13
Lead Isolation
With the Lead Isolation function selected and the Isolation Voltage key depressed, the
display will show the leakage current between the selected Patient Lead(s) and
Earth/Ground. The display is in µAmps and will read from 0 to 1999.
Attach the patient leads to the connectors on the top of the Safety Analyzer. The left and
right arrow keys may then be used to select any individual lead and all of the leads.
Internally, relays connect the leads as necessary. The LEDs indicate the selected lead(s).
As each lead and then All leads are selected, depress and hold the Isolation Voltage key.
This will apply 110% of the line voltage through a 121K resistor to the selected lead(s) and
measure the current that flows to Earth/Ground through a 1000 Ohms load with either
AAMI ES1-1993 or IEC 601 frequency compensation as selected by the Load key.
The test should be performed for all receptacle switch combinations as called out in the
Test Matrix, or a subset of these based on the manufacturer’s specifications or local codes
and protocols. This is to be done for each lead individually and All leads together.
This test measures the leakage current that would flow through the lead(s) if the patient
were to come into contact with Line voltage. This is referred to as MAP (MAINS on Applied
Parts).
WARNING
The Analyzer applies 120 or 240 VAC plus 10% to
the Patient leads or External test leads during
the Isolation test. Although this is current
limited by a 121K Ohms internal resistor, per
standard test specifications, care should be
taken to prevent contact with this voltage.
Do not touch the test leads, connections or DUT
while depressing the Isolation Test key.

14
Point to Point Measurements
The unit has the ability to measure Leakage Current, Isolation Leakage Current and
Resistance between two points, utilizing two test leads. These tests are separated
because they use a slightly different setup than the previous tests.
Point to Point Leakage Current
With the External function selected, the display will show the leakage current between the
test leads. The display is in µAmps and will read from 0 to 1999.
The test requires that the Black test cable be plugged into the Chassis Socket and the Red
test cable be plugged into the External Socket. The other end of the leads are then
attached to the points of interest.
Any current flowing between the test points is passed through a 1000 Ohms load with either
AAMI ES1-1993 or IEC 601 frequency compensation as selected by the Load key.
Point to Point Isolation Leakage Current
With the External function selected and the Isolation Voltage key depressed, the display will
show the isolation leakage current between the test leads. The display is in µAmps and will
read from 0 to 1999.
The test requires that the Black test cable be plugged into the Chassis Socket and the Red
test cable be plugged into the External Socket. The other end of the leads are then
attached to the points of interest.
Depress and hold the Isolation Voltage key. This will apply 110% of the line voltage
through a 121K resistor to the test leads and measure the current that flows through a 1000
Ohms load with either AAMI ES1-1993 or IEC 601 frequency compensation as selected by
the Load key.
WARNING
The Analyzer applies 120 or 240 VAC plus 10% to
the Patient leads or External test leads during
the Isolation test. Although this is current
limited by a 121K Ohms internal resistor, per
standard test specifications, care should be
taken to prevent contact with this voltage.
Do not touch the test leads, connections or DUT
while depressing the Isolation Test key.

15
Point to Point Resistance
With the Earth Resistance function selected, the display will show the resistance between
the two test leads. The display is in hundredths of Ohms and will read to 19.99 Ohms.
Remove any device plugged into the Analyzer Test Receptacle.
The test requires two Black (Kelvin) test cables--one in the Chassis Socket and the other in
the External Socket. The other ends should be connected to the points of interest.
Since the Black (Kelvin) cable removes any error from the test leads (providing a true 4
wire reading), the value displayed is the actual resistance of interest, without any
compensation.
NOTE: If there is a DC voltage present between the two test points, the reading may
contain an error. This can be checked by reversing the connections. If the readings differ,
average the two to get the actual resistance value.
