End the shotgun approach to troubleshooting and reduce the time spent in diagnosing altitude encoder/transponder problems. TRANS-CAL INDUSTRIES' EET-200 offers the avionics technician an inexpensive diagnostic tool for altitude encoder/transponder troubleshooting.Open or shorted wire in your encoder harness? A bad input gate on the transponder? Why waste time jumping individual data bits to ground using a clip lead and paper clip? The EET-200 provides the avionics technician a clean, quick and reasonably priced method of emulating an altitude encoder output by providing a known good altitude code source to aide in isolating each data bit D2 through C4.Simply unplug the altitude encoder and substitute the EET-200; rotating the knob will move the transponder through a variety of preprogrammed altitudes testingeach data bit in sequence.Suspect a problem with the altitude encoder? Unplug the encoder and plug both the transponder and the encoder into the EET-200. Use the built in vacuum syringe to simulate any altitude from below sea level to over 30,000 feet (using supplied 12 x 1/8 tubing, not pictured). Compare the encoder output to the supplied altitude code chart to determine if an error is present.Strobe function not working? Simply toggle the strobe switch on the EET-200 to simulate an open strobe on the digitizer or the transponder.Power supply connected correctly? Simply unplug the altitude encoder and substitute the EET-200. If the power LED glows green then your good to go, if it glows red then your power is hooked up improperly.Simple, Clean, Compact and almost indestructible. Put the EET-200 in your toolbox today!
