Editing the Test Configuration to Add References
NOTE: If you want to use references for testing, but do not want to save them to the active test
configuration, use the process for “Editing the Test Configuration to Use In-session References” in the
next section.
1. Press the Edit test configuration icon at the top of the Surge Test screen to open the active test configuration for
your selected asset.
Fig 91:
Edit test configuration icon.
2. Scroll to the bottom of the test configuration screen to find the Surge section.
3. Check the Lead 1, Lead 2, and Lead 3 boxes to enable them for a 3-phase motor (as used in this example).
NOTE: For single-coil testing, check the Lead 1 and Lead 2 boxes if you plan to test in both directions. If
you plan to test in only one direction, check the Lead 1 box only. Lead 3 is not used in coil testing.
4. Ensure that Surge Test is enabled.
5. Check the Zero Start Override box if you want to use this feature.
6. Touch the drop-down list for Reference Waveform 1 then select the reference created earlier in the process for Lead
1. The name and reference waveform will appear as shown in the example below.
NOTE: You can create up to three references for 3-phase motors, and up to two references for single coils.
In some cases, only one reference will be used for all three phase measurements. Leaving Reference
Waveform 2 and 3 blank will apply Reference Waveform 1 to all other measurements.
For single coils, if only one reference waveform is used, and both Lead 1 and Lead 2 are selected, the
software will use the same reference when surging in each direction of testing when using the Coil Test
screen.
7. If required, select the references for Reference Waveform 2 and 3.
8. PPEAR+ Limit cannot be used in conjunction with Zero Start Override; checking the Zero Start Override box will
automatically uncheck the PPEAR+ Limit box.
9. Set the Coil Reference Limit to the maximum allowed percentage of wave area deviation compared to the reference.
NOTE: Using Zero Start Override is not required. In some cases, ramping the target voltage provides a
more precise indication of the point where an issue occurs. Jumping directly to the target voltage might
miss the point in the waveform where such an issue occurs.
