RETURN
Purpose Start a new generation using the current target pressure.
Command “RETURN”
Classic “RETURN”
Remarks The “RETURN” program message will start a new pressure generation using the
current settings and target pressure. Generation will continue until a new target
pressure is set, the PPCK+ goes into LOCAL mode, or an “ABORT” program
message is executed.
Example
(enhanced) Cmd sent:
Reply: “RETURN”
“1000.000 kPaa” (no reply if IEEE-488)
Example
(classic) Sent:
Reply: “RETURN”
“1000.000 kPaa”
Errors ERR# 6: The current target pressure is invalid.

RS
Purpose Adjust pressure at a fixed rate.
Command “RS RateReq ”
Classic “RS= RateReq ”
Arguments RateReq: The rate for the PPCK to generate to. Negative rates cause the
pressure to decrease and positive rate cause the pressure to
increase.
Remarks The requested rate is an approximation, and the PPCK will set and maintain a rate
near to the requested rate to be the best of its ability. Actual rates that can be set
depend on the volume of the device under test. The PPCK+ will continue to maintain
the rate given until the “ABORT” command or [ESCAPE] key is used to cancel the
operation, or the UL pressure is reached.
