HP-35 Power Supply Waveforms

[AndiGer]

Dear Alberto,

looking at the guide (page 6 in turn to page 7) I am not sure voltages are off load.

Quote:This is all you can do with the logic board removed, so now
install the logic board, and connect power to the battery contacts.
Measure Vbsw again to make sure it hasn’t dropped too far below the
original value. Also, measure the voltage at pin 2 of T1 to check if it
is the same as Vbsw. Now measure Vcc, Vss and Vgg.
Vcc should be just around 8.2V.
Vgg should be about –12.4V
Vss should be about 6.28V

EDIT: In the working unit I think you measured anything installed as well?
