ST2883 Series Operation Manual                                            Chapter 7 User guide 

7-5 

7.4.5  Chart for differential area 

In the process of BDV test, the secondary display zone displays not only the extraction value of the corona 
but also the chart record of differential area after each test. The chart can help user observe the changing 
regularity of the area differences during the test from the start voltage to the end voltage.
