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.
