Note: For capacitance > 1000F, add 2% per another 1000F for Dissipation Factor. For capacitance > 1000 F, add 0.5 per another 1000 F for -25+20 Impedance ratio. Add 1 per another 1000 F for -40+20 Impedance ratio. Pre-treatment for measurements shall be conducted after application of DC working voltage for 30 minutes.
