Error Messages
All remote commands sent to the CPC3050 are shown in the Trouble Shooting App, under the “Remote”
button. If there is a syntax error, an error message will appear below the errant command. Local errors
and remote command errors will appear under the “Error” button. Maximum of 100 errors are stored and
can be retrieved.
The error messages can also be seen remotely by sending “Error?” to the instrument.

7.6 SCPI Command Set
7.6.1 SCPI Commands and Queries
The WIKA SCPI command is compatible with older WIKA instruments such as the original CPC8000
Notes:
1. Note that WIKA and Ruska 7010/7250 Emulation return slightly different responses to some queries.
2. Except for the engineering units selection, the numeric suffix selects the applicable transducer [R]:
1 = Sensor 1
2 = Sensor 2
This numeric suffix [R] always defaults to the active transducer if not specified.
3. Ruska 7010/7250 SCPI command set is identital to SCPI WIKA command set except
• Numeric responses have 1 additional digit of resolution
• Responses YES/NO return as 1/0
• All responses are capitalized
• String responses are enclosed in double quotes e.g. OUTPut:MODE responds wth “VENT”,
“MEASURE” or “CONTROL”
• Multiple commands may be sent at once seprated by a semicolon ;
• Example: SOUR:PRES:LEV:IMM:AMPL 1.0;OUTPut:MODE CONTROL;MEAS:PRES?
• This will process 3 commands:
1. SOUR:PRES:LEV:IMM:AMPL 1.0 => change setpoint to 1
2. OUTP:MODE CONTROL => change mode to control
3. MEAS:PRES? => read the current pressure
