94/104 Agilent 4UHV Ion Pump Controller User Manual / 87-900-137-01 (A)
Changing the Output Voltage
To change the output voltage choosing between 7KV, 5KV, 3KV, Step-
Mode and Fixed-Mode, keep the Fixed Step key pressed while you
press the HV-x key, where x is the number of the channel for which
you want to change the output voltage.
The output voltage changes cyclically between “STEP 7 KV, 5 KV, 3
KV”.
Menu
Keeping the “Mode” key pressed for a long time (> 2 sec), you enter
the Menu. In the Menu, you can configure some parameters of the
controller. These configurable parameters can be divided into two
groups:
Controller general parameters
Specific parameters for each channel.
The general parameters of the controller are the following:
Pressure measurement unit: mbar, torr, pascal
Serial baud rate: 1200, 4800, 9600
Serial Type: RS232, RS485
RS485 Address: from 0 to 31
Auto start: Yes, No
Fan: Always on, switches on if the current descends below 1mA
Set Point: The set-point can be associated with the channels and
a value set
Analog output: Analog output is associated with the channels.
The specific parameters for each channel are the following:
Pump: Select the type of pump
I Protect: Set the Protect current
