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.
