4. Measuring process
4.1 Set the test sequence and parameters range as to the stator parameters and establish a new model for this type of stator (The model of one stator type needs to be established only for the first time)
4.2 Put the tested stator on a designated station and clamp it
4.3 Press the two start buttons to test and the “in-test” indication light is lightening.
4.4 All the items will be tested. The operator is not allowed to touch the stator during the test.
4.5 Pass or fail signal will be triggered after completing all items test.
4.6 Take out the tested stator and continue to test next one from step 2.
