measuring the charge care must be taken to ensure that:

(a) a.c. coupled devices such as current transformers are not affected by prior passage of

high amplitude forward current.

(b) A suitable, polarised, clipping circuit must be connected to the input of the measuring

oscilloscope to avoid overloading the internal amplifiers by the relatively high amplitude

forward current

(c) Measurement of reverse recovery waveform should be carried out with an appropriate

critically damped snubber, connected across diode anode to cathode.
