7.5.2 SETTING OF CURRENT LIMITING
The spray current limitation can be set and measured independently in both of the control
unit's channels. If the measured spray current reaches or exceeds the set value, the high
voltage is adjusted downwards until the set spray current is reduced to maximum.
The current limitation can be prede ned in 1 μA steps between 5 and 120 μA.
The graphic shows the characteristic curves for three di erent current restrictions.
You can see from the blue curve that the voltage reduces quickly with a low current
restriction.
