Re: 576 CT no step generator current but voltage steps OK
Hi Ed,toggle quoted messageShow quoted text
Please ignore this if you tried already.
Set the left-off-right switch to off, steps to 1, base current at 10 uA steps, horizontal at base voltage 2 V/div. The base voltage choice terminates the base current in 1 M. So you should see a dot at 0 V and a dot at 10 V. If you increase the number of steps you will note compression above 12 V or so.
The test fixture is not involved, unless it leaks B to E somewhere, very unlikely in OFF position.
I don't know where base voltage is sensed internally. If you see the same check result when you choose Left or Right and short B to E there, there likely is an interruption between sense point and B terminal.
