1/ There shall be no evidence of shorts of the ignitor electrodes as indicated by a short indicator during vibration.
2/ Ignitor interaction is measured with the specified ignitor current adjusted on both ignitor electrodes.
3/ Ignitor ignition time shall be measured separately for each ignitor electrode.
4/ Ignitor voltage drop shall be measured separately for each ignitor electrode.
5/ All measurements that include short-slot hybrids shall be made with gaskets bolted between input and output flanges of tube and
mating flanges.
