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 reference .
