2.How to choose the suitable products for test
Please make sure that the capacitance of test products is below the instrument rated capacitance. The waveform will be influence if the
capacitance of test products is too small and the instrument can not
normally output when it below 0.05µF. 0.1µF capacitor in parallel to
auxiliary output. Below is capacitance of some instrument for your
