Power Supply Calibration?
« on: May 13, 2013, 02:37:29 pm »
Hi

I had to repair my E3644 and now it needs a calibration. I dont fancy sending this heavy beast away, so I'd prefer do to it my self.
So the question is how could I calibrate this to get it close to its specs? I'm considering buying a bench meter (3478 or 3457). With either of those the voltage part should be ok?
What about the current part? Could a homebuilt dummy load do or is it prefered to use a proper programable electronic dc load? Service manual suggest a 0.01ohm , 0.01% shunt tho, which I dont have.

Either calibrate it against your own multimeter, or look out for another electronics guy in your neighbourhood. Maybe go doorbell ringing to the next tv repair shop.
