unsuccessful autotune
Dear Frinds,
I tried to tune the system manually.
from the last autotune the multiplier voltage was very high (2,358)
I reseted the multiplier without installing a new one and I didnt know how to encrease the voltage again.
so on the voltage 1200 I could see only the amu of 131 not any higher value (I couldnt see 219 or higher at all).
so do you think its only multiplier problem or I should do sontheng else.
this results after a good cleening for the ion catridge and ion guide.
please help.
regards.
