Can anyone remember how to run a 'confidence
test' on the 7475? Pressing
2 buttons at once, and holding down a button while powering up doesn't
seem to do it. Nor does setting the HPIB address to 31 (normally illegal,
of course).
Tony,
I don't have a 7475 in front of me, but here's the steps to
initiate the self-test:
1. Turn off power
2. Load pens
Pen 1 = Black
Pen 2 = Black
Pen 3 = Red
Pen 4 = Green
Pen 5 = Blue
Pen 6 = Violet
3. Load paper
4. Hold P1 and P2 down
5. Turn on power
6. Release P1 and P2 when plotting begins
Cheers,
Dan
