Running the Manual Armature Surge Test Using the Baker ZTX
NOTE: In most applications, you will need help from another person to complete at least the first part of this test
process: obtaining the reference waveform. One person will operate the fixture on the armature while the other
operates the tester.
CAUTION: Ensure that both operators clearly understand the process and how to use the software. The fixture/
probe operator must know how to properly use the ATF-5000 or test probes to avoid injury from electrical shock, or
damage to the test equipment or the unit under test.
1. For this example, a new Motor ID for the armature and a new Test ID have been created. For your application,
ensure that you have selected the proper Motor ID and Test ID for your armature.
2. From the Tests tab, ensure that the selected Test ID has the Surge Test turned ON and that the section is labeled
"Surge Test Using AT101ZTX."
3. Click on the test configuration button at the end of the Surge Test row to open the Surge Test setup window.
Because this is a manual test, it is run from the Surge Test - Armature window.
4. The AWA operator must ensure that the Voltage Output Control knob on the AWA front panel is at zero;
turned fully counter-clockwise.
5. The armature operator will position the test fixture (or probes) on the first bar and the second bar (adjacent to
the right); bar 1 will be the reference bar. Bars are tested in a progressing sequence of 1–2, 2–3, 3–4, and so on.
6. When both operators are ready, the armature operator will hold down one of the test buttons on the ATF-5000
(or footswitch if using probes), then the AWA operator will ramp the voltage to the desired level.
7. After the first bar is tested and you are satisfied that you have a good reference waveform, the AWA operator
will click on the Set Ref button. This establishes the reference for the remainder of the test and sets the tester's
target voltage level.
8. In the following example, the target waveform is acquired from bar 1, so the Set Ref button is pressed.
