First published in 1942, Zeigler and Nichols described two methods of tuning a PID loop. These work by applying a step change to the system and observing the resulting response. The first method entails measuring the lag or delay in response and then the time taken to reach the new output value. Dec 10, 2015 PID Tuning Method The determination of corresponding PID parameter values for getting the optimum performance from the process is called tuning. This is obviously a crucial part in case of all closed loop control systems. Theoretically, the most basic PID auto-tuners simply automate the manual PID tuning procedures: force a change in the controller effort (bump or step tests), observe the results, and adjust the tuning parameters.

Hey guys wondering if anybody can help, i've had a google and searched about but i think it's better to just ask as i read mixed stuff.
I've just upgraded to scratch pro 2.
I'm using two 1210's, Audio 8.
When i attempt to calibrate the decks 9/10 times it says 'Unknown Medium - Low Input', some times it works but usually loses track again pretty quickly.
Now i'm using pretty shitty carts/stylus (battered stanton 500's), and my tables aren't perfectly even, but records sound fine.
No problems with grounding, as records are fine (Grounded to A8 anyway). Tracking weights on 3.5 and 3.3 (I have mismatched headshells), antiskate 3.
Is the input to the adc just THAT low?
I've played on even more ghetto setups than mine using serato and never had this problem.
If it's the carts, not a massive deal as i'm getting some m44's anyway once i got the cash. (For a stop-gap, would these work http://www.ebay.co.uk/itm/350397205578 ?)
And one last question, i bought the A8 second hand on ebay - the 'Input Mode' button doesn't have the same click (or appear to actually do anything, leds don't change) as the Source and Mic/Line, but is this just because scratch 2 doesn't allow input switching outside of preferences? If not i've been jipped a bit.
Cheers
