Hi Mark,
I have a couple of questions, and hope you can help with their answers. In using the 250ext, the interface was tricky because of the high "typematic" rate. You would overshoot your target, then go back with ten more button presses to hit it. I called it the interface of a thousand button presses, I know this was fixed in a repair release, but in the mean time, we all moved on to the 255 plans.
My question is regarding exactly how the 255 interface works, if you know yet. Obviously there is some combination of knob presses, knob twists, probably short and long knob presses to enter modes to select functions and others to set values. So please describe:
How do you enter the function-change mode?
Do you press the knob to move through the functions or twist it?
How do you get into value-change mode?
How long, in seconds, do you ever need to hold in the knob?
Is a quick press of the knob used? For what action?
Does it always return to Amps? If so, do you then just twist the knob, or do you press, or tap, the knob then set the amps value?
Please walk me through this interface once before it shows up, thanks.
My second question is regarding the knobs. Oleg gave me hope earlier in this thread that you had found better knobs for the 255, is that so?
Thanks for any info on this. I really hope this interface will be helpful to the operator, rather than cumbersome.
Jim
