ROUGH TO BASE
Purging is completed and the pump is being roughed to a base pres-
sure. This is displayed showing the actual pressure, and the base
pressure it is attempting to reach. The commands for this
information are
L
actual pressure
P3? Pressure attempting to reach (programmed value)
Example:
ROUGH 325u/100u = ROUGH actual pressure/try to reach pressure
ROUGH L u/P3?u
NOTE: If this is a multi-pump system, the pump roughing valve may
be waiting to use the valve.
The valve use is controlled by a token pass. Use the following com-
mand to access this information,
Command Q? A response of 1 means the pump has the token.
A response of 2 means the pump needs the token.
ROR (Rate-of-Rise): In this display we show how many rate-of-rises
have been done the actual rate-of-rise and the rate-of-rise it is
attempting to reach (the programmed value).
The commands for this information are:
m
ROR#
n
Last ROR value (actual rate-of-rise for most recent test)
P4? Programmed value for ROR
Example of Display:
