CONT
n
Purpose Have the RPM4-E-DWT reply continuously as each new measurement becomes available.
Query “CONT
n
?”
Classic “CONT
n
”
Optional Suffix
“n”
A suffix may be used instead of “
RptLabel
”
‘1’ Specify the Hi Q-RPT
‘2’ Specify the Lo Q-RPT
Remarks This command is somewhat different than most as it enables the RPM4-E-DWT to continuously
output the selected Q-RPT’s measurement without further queries. This continues until the next
query is received by the RPM4-E-DWT, or if the ABORT” or “*CLS” command is received. The
frequency of the measurements is determined by the read rate 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
(enhanced) Query sent:
Query reply: “CONT1?”
“1936.72 kPa a” (repeats every measurement cycle)
Example
(classic) Query sent:
Reply: “CONT”
“1936.72 kPa a” (repeats every measurement cycle)
See Also “PR”, “READRATE”
DATE
Purpose Read or set the RPM4-E-DWT date.
Command
Query “DATE
date
”
“DATE?”
Classic “DATE=
date
”
“DATE”
Arguments
date
: The date in the numerical only format “YYYYMMDD”
Remarks The RPM4-E-DWT 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.
Example
(enhanced) Cmd sent:
Query reply: “DATE 20030115”
“20030105”
(No reply if GPIB-488)
Example
(enhanced) Cmd sent:
Query reply: “DATE? 20030105”
“20030105”
Example
(classic) Sent:
Reply: “DATE=20021201”
“20021201”
Errors ERR# 6: Missing or improper program message argument(s).
See Also “TIME”
3.9.5.3
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
(classic) Sent:
Reply: “ERR”
“Numeric argument missing or out of range”
