controller.
The accessory P001 connector should be left in position including the jumper

Pressure Determination
The bar graph at the left gives the indication of the pressure into the
pump. The left scale is for Mini Pump, the right one for the 2 l/s
pump.
62/72
Plug the controller power cable into a suitable power source.
Place the ON/OFF switch in the ON position.
Monitor the VacIon pump current and the controller high voltage
output by watching the LED lit, then read the corresponding
current and pressure values
If only the first LED of the bar graph is lit, the current drawn by
the pump is less than 10 nA and the voltage output is 3 kV.
If the entire bar is lit and the High Load LED is blinking, this
means that the current is higher than ≥1 mA.
