Tektronix 2465A Oscilloscope Repair - Part 10

CAL 05 – Hours ON and PWR ON/OFF Cycles

This routine simply allowed me to set the Hours and Power cycles to whatever number I wanted.

 
CAL05 – Start

Steps a – d start the procedure and reset the Hours and Cycles to zero.  I didn’t bother changing them to some random number, because it would have no meaning in a 30 year old scope.  I just left them at zero and exited the routine.
