Short Circuits
If there is a short circuit between the anode and cathodes in the
pump (or cathode to pump body), the short-circuit current of the
control unit will be drawn and low voltage will be indicated. If a
short circuit exists in the control unit or high voltage cable and
connector, low voltage will also be observed when the high voltage
connector is disconnected from the pump (refer to the control unit
manuals). An ohm meter reading on the pump feedthrough may not
be effective in finding a short. Short circuits may be caused by
mechanical shock to the pump. If the pump is shorted, contact
Agilent.
