RPM4/HPMS A70M/A20M-AF OPERATION AND MAINTENANCE MANUAL
© 2007 DH Instruments, a Fluke Company Page 84
CONTn
Purpose Have the RPM4 reply continuously as each new measurement becomes available.
Query “CONTn?”
Classic “CONTn”
Optional Suffix
“n”
The active Q-RPT is assumed if no suffix is given.
‘1’ Specify the Hi Q-RPT
‘2’ Specify the Lo Q-RPT
Remarks This command is somewhat different from most as it enables the RPM4 to continuously output the
selected Q-RPT’s measurement without further queries. This continues until the next query is
received by the RPM4, or if the ABORT” or “*CLS” command is received. The frequency of the
measurements is determined by the readrate of the Q-RPT. The data returned includes the
pressure of the specified or active Q-RPT, current unit of measure and measurement mode.
Example

“DATE date”
“DATE?”
Classic “DATE= date”
“DATE”
Arguments date: The date in the numerical only format “YYYYMMDD”
Remarks The RPM4 has an internal real time calendar clock. The span of acceptable dates ranges
from 19800101 to 20791231. The reply is always in the YYYYMMDD format.

3.5.5.3
ERR
Purpose Read the new available error message from the Error Queue.
Query “ERR?”
Classic “ERR”
Remarks This program message obtains additional details about an error that has occurred. If the user
receives an “ERR# nn” reply, or the enhanced mode is enabled using the IEEE-488 interface and
an error has been detected, the error is put into a FIFO Error Queue. The “ERR” program
message pulls and replies the oldest error message available. In “classic” mode only the most recent
error can reside in the queue. “OK” is replied if there are no error messages left. If an error occurs in
enhanced mode using the IEEE-488 interface, no reply is generated even if the command was a
query.
Example
(enhanced):
Query sent:
Query reply:
“ERR?”
“Numeric argument missing or out of range”
Example
