CRVDEL Curve Delete Command
Input
CRVDEL <curve>[term]
Format nn
<curve> Specifies a user curve to delete. Valid entries: 21 to 59.
Example CRVDEL 21[term] —deletes User Curve 21.
CRVHDR Curve Header Command
Input
CRVHDR <curve>,<name>,<SN>,<format>,<limit value>,<coeffi-
cient>[term]
Format nn,s[15],s[10],n,+nnn.nnn,n
<curve>
Specifies which curve to configure. Valid entries: 21 to 59.
<name> Specifies curve name. Limited to 15 characters.
<SN> Specifies the curve serial number. Limited to 10 characters.
<format> Specifies the curve data format. Valid entries: 3 =
)
/K (lin-
ear), 4 = log
)
/K (linear), 7 =
)
/K (cubic spline).
<limit value> Specifies the curve temperature limit in kelvin.
<coefficient> Specifies the curves temperature coefficient. Valid entries:
1 = negative, 2 = positive.
Example CRVHDR 21,”RX-102B”,”00011134”,4,1.5,1[term] —configures user curve 21 with
a name of RX-102B, serial no. 00011134, data format of logohms vs. kelvin using lin-
ear interpolation, setpoint limit of 1.5 K, and negative coefficient.
Remarks Configures the user curve header. The coefficient parameter will be calculated auto-
matically based on the first 2 curve datapoints. It is included as a parameter for com-
patability with the CRVHDR? query. When in 370 emulation mode, the user curves are
defined as 1 to 20 for backwards compatibility.
Be sure to use quotes when sending strings, otherwise characters such as spaces and
other non alpha-numeric characters will be interpreted as a delimiter, and the full
string will not be accepted. It is not recommended to use commas or semi-colons in
curve names or serial numbers as these characters are used as delimiters for query
responses.
