The starting count value is the threshold value where the analyzer switches from starting mode to normal mode.
If the cell count value (value from the analog to digital converter; this value may be observed under diagnostic menu) is
under the starting count value, a higher power is applied to the cell by the plasma generator. Once the plasma is started,
the cell count will be higher than the starting count value and the power will come back to normal. If, for any reason, the
cell count value with the normal power applied to the cell is too close or oscillates around the starting count value, the
analyzer will go back and forth between starting and normal mode.
To get rid of such a situation, you should enter a new (lower) threshold value.
To enter a new value, just use the numerical key on the keypad followed by enter key ("E" key). The value must be
between 0 and 1,000,000 counts.
The default value is normally just what the system needs and, under normal conditions, this value should not be changed.
From this menu, by selecting "F3" for next sub-menu, the following menu is brought up on the display.
