Running the Test
Before actual test data can be acquired, the pre-test must be run. This is accomplished in the Pre-Test
window. As its name implies, the Pre-Test window centralizes functions that, following test setup, need
to be performed prior to running an actual test. This includes running preliminary tests to measure
quantities that are subsequently used to set test limits for Class C and Class D devices. Once the pre-test
data is available, the main test can be started. This is accomplished in the Test window. Test status
information is displayed in the Status bar on the bottom of the screen. Note that you must always have
pre-test results present before running the main test.
