Procedure

Overview

This appliance is intended for professional use only. Before using the
appliance, the user must read this instructions manual carefully and
any other additional information provided by Agilent. Agilent
declines any responsibility for total or partial non-compliance with
the instructions, improper use by untrained personnel, unauthorized
operations or use contrary to specific national regulations.
Ion Pump HV P.S. is a power supply that is used to power ion pumps
during transportation phases in order to prevent air entering the
pump.
The power supply uses a 9 V non-rechargeable battery positioned
inside or, alternatively, may be connected to an external power source
able to provide a DC voltage of 9 V with greater autonomy.
All the information required to guarantee operator safety during use
of the appliance is provided below.

Principle of Operation

The unit is able to determine whether or not the pump connected is
active. When the HV is ON, the unit measures pump current:
if the current is less than 50 nA, the discharge inside the pump is
OFF (red LED L1 blinking); if the current exceeds 50 nA, the pump is
operative (green LED L2 blinking).
The unit generates the HV that powers the ion pump when the power
switch is set to ON.
