Command
Query
“RES n ”
“RES”
Classic “RES= n ”
“RES”
Default “RES 0.001”
Arguments n: The pressure display resolution in % span of the current RPT range (0.0001 to 1 % FS).
Remarks The pressure display resolution is defined as % span of the active range. The setting is
separate for each range, and changes as the range is changed.

RESET
Purpose Reset the user’s settings to factory defaults.
Command “RESET”
Classic “RESET”
Remarks The PPC4 has user settings (units, resolution, control modes, etc.) that can be reset to factory
defaults. System calibration coefficients and communications settings are not affected. The
remote “RESET” program message corresponds to the front panel “Reset Settings.” The reset
cycle takes up to 5 seconds to complete and involves a power cycle of the PPC4. Remote
communications should not take place during this period.

pressure.
Command “RETURN”
Classic “RETURN”
Remarks The “RETURN” program message starts a new pressure setting sequence using the current
settings and target pressure. Pressure control continues until a new target pressure is set, the
PPC4 is put into LOCAL mode, or an “ABORT” program message is executed.
