With the SBS in conduction and the relay contacts open, close the contacts to cause anode A2 to be driven negative. Decrease C until the SBS just
remains off when anode A2 becomes positive. The turn off time, toff, is the time from initial contact closure and until anode A2 voltage reaches
zero volts.
Turn-on time is measured from the time VS is achieved to the time when the anode voltage drops to within 90% of the difference between VS
and VF.
