Continuity heater probe, part number PN BH3810-40, is a special-function probe designed to apply heat individually to exhaust gas temperature EGT thermocouples to determine whether all thermocouples are operating. Application of the pre-heated probe to a properly operating thermocouple causes a slight temperature increase on the aircraft EGT indicator. TEMPCAL heater probe, PN BH1278, is a clamp-type heater probe designed to check operation of continuous-loop-type overheat fire warning detectors under heated conditions. Application of temperature equal to the aircraft system fire warning trip point causes the fire warning light to activate. The continuity heater probe performed its intended function satisfactorily.
