1. Instrument Descriptions
Baker AWA-IV 2 kV/4 kV Model Front Panel
All Baker AWA-IV series analyzers feature an eight-inch touch screen with a graphical user interface.
The interface features a logical layout of touch icons that improve ease of use.
Each tester’s voltage capacity is identified by the markings found just below the touch screen.
Figure 1. Front panel controls for AWA-IV 2 kV and 4 kV models.
VGA port
The VGA port is used to connect the tester to a larger monitor (not included) foreasier viewing of
test results.
USB ports
Industry standard USB ports are accessible from the front panel for connections to aprinting device,
and data storage and retrieval devices.
Ethernet connector
The tester can be connected to a network via the ethernet connector.
Equipment stop button
This large, highly visible red button is easily pressed for immediate termination of high-voltage
testing. It disconnects all high voltages from the test leads.
Instrument Descriptions

Instrument Descriptions
Low-voltage resistance test leads
Both sides of the connection clips must be in contact with the terminal of the motor being
measured. Most recent AWA-IV 2/4kV testers have two low-voltage resistance test leads. Ensure
that the leads are connected as shown in the example below.
Figure 2. Proper orientation of AWA-IV 2/4 kV 2-lead connectors.
AWA-IV6 analyzers use the high-voltage leads for low-voltage resistance testing (no additional set
of leads).
AWA-IV 12kV analyzers have three red test leads for low-voltage resistance testing (no black lead).
High-voltage test leads
The Baker AWA-IV uses high-voltage test leads for surge, Baker ZTX, and DC testing. You must
keep the leads clean and dry for best measurement performance.
The AWA-IV 6 KV model differs from the AWA-IV 12 kV with respect to test leads and procedures
for use.
The AWA-IV 6 kV analyzer uses only one set of leads for both high- and low-voltage testing; it does
not include a separate set of low-voltage test leads (shown as “low voltage resistance test leads” in
the image).
Voltage output control knob
Turn the knob clockwise to increase the applied voltage or counterclockwise to decrease the
voltage.
The rate of voltage increase or decrease is set via the touch screen interface.
Do not force the knob; turning the knob harder does not cause voltage to ramp any quicker and
may damage the instrument.

8. When you are satisfied with your specifications, close the Surge Test setup screen.
When you have completed the processes for selecting an existing motor ID, creating a new motor
ID (and Test ID), selecting tests to run, and confirming or modifying test parameters, you will be
ready to run the tests on your motor. Details for running tests automatically, semi-automatically, or
manually are provided in the next section along with other operating procedure information.
Surge testing through capacitors
The surge test is load dependent. Anything that adds capacitance to the motor or system under test
will create more load on the tester.
When surge testing a motor, all capacitors should be removed or the ground should be lifted.
Otherwise, the capacitors will absorb the surge pulse, preventing it from entering the coils.
Rotor effect on testing
When possible, remove or secure the rotor before testing. Rotors can affect testing results,
particularly if they move (even slightly) during testing.
Some issues can be erroneous high resistance imbalance in coil testing due to increased inductance,
inability to polarize for DA/PI testing,or frequency shift in one or more waveform values during
surge testing.
An erratic PP EAR will often result, and the shift could even trip the EAR limits.
