PUMP 0 to 10 volts, microprocessor control range (0
to 255 percent) to the pump. 0 volts represents
1.55 volts to the pump; 10 volts represents 12
volts to the pump. Pump voltage = P (12) + (1-
P) (1.55) where P = pump.
HOST 0-11 volt signal that can be set by a [HOST]
computer via the RS-232 port. This mode is
useful when controlling an instrument such as
the Electrostatic Classifier with the 3022A CPC
as part of a DMPS or SMPS system.
