Single-Phase Testing - Megger Baker AWA-IV User Manual

Single-phase Testing

When performing single-phase testing (for example, on DC motors or when testing single coil) you must use this
setup window to set the parameter that alerts the tester to operate in single-phase testing mode.
1. From the Tests tab, click on the test configuration button at the end of the second/Resistance row in the
Temperature/Resistance Tests section.
2. Click on the Temperature Enable radio button if you will be using temperature compensation.
3. Click on the Resistance Enable radio button to enable the parameter options in this area.
4. Click on 2 Leads (1 phase) and check the Res Leads box. Notice that the list of leads to test in the Test Results
section changes to include only one set (Lead 1–2).
5. You can leave the Resistance Enable radio button active if you choose to run resistance tests, or turn it off if
not. However, you must ensure that the 2 Leads (1 phase) radio button is selected and the Res Leads box is
checked to enable single-phase testing.
NOTE: The Temperature/Resistance Test setup window is the only place where you specifically define parameters to
enable single-phase testing. All other tests function in the same manner as they would for 3-phase testing, except
that the software knows to use only test leads 1 and 2 during those testing steps.

6. Set up parameters for DC and Surge tests as needed for the device using the respective setup windows. No
specific parameter in either window will directly affect single-phase testing. The tests are set up and conducted
the same as they would be for 3-phase testing, except that only leads 1 and 2 will be used.
