Setting the Balance
The output of the 977CM can be biased to negative or positive. The adjustment
changes the percentage of time that each HT output is switched on. The maximum bias
is 80% to either positive or negative.
Changing the balance of the output changes the relative amount of positive and
negative ions produced by the ioniser. With the help of a static locator the balance can
be adjusted for more accurate neutralisation of the target material.
