The accuracy of the test voltage measurement shall be as specified in Table 1. NOTE The verification of electrode output voltage should
18、 consider electrical structure of ESD generator (e.g. electrical circuit structure) and specification (e.g. input impedance and input stray capacitance) of high-voltage meter for correct measuring. A.2.3.4 The measurement discharge current procedure is shown in Table A.1. The following parameters sh
