RATE
Purpose
Read the next available pressure rate of change.
Query “RATE?”
Classic “RATE”
Remarks
The next available pressure rate of change in the current pressure unit per second is
returned.
After receiving this program message, the PPCH-G replies back with the data once a new
pressure measurement cycle is complete. This can take up to 1.5 seconds.

READYCK
Purpose
Read or set the
Ready
check flag.
Command
Query
“READYCK 1”
“READYCK?”
Classic “READYCK=1”
“READYCK”
Remarks
The internal ready check flag is cleared whenever the PPCH-G reaches a
Not Ready
(NR)
condition. The “READYCK” query returns the status of the flag. Sending the “READYCK 1”
program message while the PPCH-G is in a
Ready
condition sets the flag. The “READYCK”
program message query can then be used at a later time to determine whether a
Not Ready
condition has occurred since the ready check flag was set.

REMOTE
Purpose
Lock out the front panel keypads during remote operation.
Command “REMOTE”
Classic “REMOTE”
Remarks
The PPCH-G goes into remote mode whenever communications take place. The user can
return to local operation by pressing the [ESC] key. The REMOTE program message locks
out the front panel completely. The only way to unlock the front panel after the “REMOTE”
command is using the “LOCAL” program message, the IEEE-488 “GTL” command, or by
cycling the PPCH-G power. A transition from remote to local operation aborts any current
pressure control.
