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 Polarity key has a 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.
Patient Lead Control
There are ten patient leads. 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 and an internal relay for each lead. The LEDs and the markings to the
right of each LED indicate when that relay is on, thus selecting the indicated lead. The
Up and Down 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 “ISO” Test key is depressed. It is only active in
the Lead Isolation mode. It is a momentary key so that High Voltage is only applied
while the key is held down.
Waveform Selection
When the ECG Waveforms function is selected, the two keys and 10 LEDs become the
Waveform Selection Control Section. The markings on the left side of the LEDs are
used during these tests. The LEDs indicate which waveform is generated. The Up and
Down arrow keys sequentially select each waveform. The microprocessor sends the
selected waveform to a Digital to Analog converter that generates an accurate analog
representation. This waveform is then sent through a resistor network, developing the
appropriate signals on the output terminals.
Power Outlet Indicators
Three Neon indicators help verify the polarity and wiring of the wall receptacle that the
Safety Analyzer is plugged into.

8
HI Level Output (+)
A HI Level connector is located on the side of the unit for the high level ECG output
signal (1 V p-p). The connection is between the High Level (+) snap and the RL (-) ECG
lead.
Self-Test Snaps
There are two snaps 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
leakage current source to Earth/Ground when the Chassis lead is applied and the
Analyzer set to the proper mode.
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.
Test Receptacle
This receptacle is for the connection of the DUT. The Receptacle Rating depends on
the specific Analyzer model. SA-2010S models use a Hospital Grade North
American/USA standard NEMA 5-20R receptacle rated 20 Amps @ 125 VAC. SA-
2010S-INTL models use a universal international receptacle rated 20 Amps @ 250
VAC. SA-2010S-AUS models use an Australian-specific AU1-10R receptacle rated 10
Amps @ 240 VAC. An external patch cord may be necessary to connect devices
utilizing different types of plugs to the Analyzer receptacle.
Power Cord
The Power Cord, which is connected internally, provides power to both the Safety
Analyzer and the DUT through the Test Receptacle. The Power Cord varies depending
on the Analyzer model. SA-2010S models use a NEMA 5-15P plug designed to plug
into a NEMA 5-15R or 5-20R Receptacle. SA-2010S-INTL models have a short IEC
C20 plug for which a country-specific adapter cable must be connected –See the
following section for this information. SA-2010S-AUS models use an Australian AU1-
10P plug intended for operation with Australian and New Zealand AU1-10R
Receptacles.

9
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 over this communications link as well as full control over all analyzer
functions and settings. For further details, see the Communication Protocol section.

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.
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.
TESTING
NOTICE –PERFORMING TESTS

TEST PROCEDURES AND MEASUREMENT LIMITS.

11
Device Current
With the Device Current function selected, the display will show the current draw of the
DUT. The Receptacle should be configured with HOT-CLOSED, NEUTRAL-CLOSED,
GROUND-CLOSED and POLARITY-FWD. Refer to the Specifications section for
current capacity and permitted duty cycle for this test mode.
Earth Resistance
With the Earth Resistance function selected, the display will show 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 of 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. Over-range shows as
“1_ _ _”.
Earth/Ground Leakage Current
With the Earth/Ground Leakage function selected and the Ground-Open, the display will
show the leakage current in the ground wire of the DUT.
NOTE: This test has no meaning for equipment that does not use a grounded cord.
Selecting this function automatically opens the connection to Earth/Ground and passes
any leakage current through a 1000 Ωload with either AAMI ES1-1993 or IEC 601
frequency compensation as selected by the Load Selection switch.
Enclosure Leakage
With the Enclosure function selected, the display will show the leakage current between
the Enclosure (Chassis) and Earth/Ground.
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 a 1000 Ω
load with either AAMI ES1-1993 or IEC 601 frequency compensation as selected by the
Load Selection switch.

12
Lead to Earth/Ground Leakage
With the Lead to Earth/Ground function selected, the display will show the leakage
current between the selected lead and Earth/Ground.
Attach the patient leads to the connectors on the top of the Safety Analyzer. The Up
and Down arrow keys may then be used to select any individual lead or all of the leads.
This test should 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.
Attach the patient leads to the connectors on the top of the Safety Analyzer. The Up
and Down arrow keys may then be used to select any individual lead. Internally, relays
connect the leads as necessary. The LEDs indicate the selected lead.
This test should 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.
Lead Isolation
With the Lead Isolation function selected and the “ISO” Test key depressed, the display
will show the leakage current between the selected Patient Lead(s) and Earth/Ground.
Attach the patient leads to the connectors on the top of the Safety Analyzer. The Up
and Down arrow keys may then be used to select any individual lead and all of the
leads.
WARNING
The SA-2010S applies 110% of line voltage to the
Patient leads or External test leads during the
Isolation test. Although this is current limited by
a 121 kΩ 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.
