CRVDEL Curve Delete Command
Input
CRVDEL <curve>[term]
Format nn
<curve> Specifies a user curve to delete. Valid entries: 21–59.
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: 21–59.
<name> Specifies curve name. Limited to 15 characters.
<SN> Specifies the curve serial number. Limited to ten characters.
<format> Specifies the curve data format. Valid entries: 1 = mV/K, 2 = V/K,

3 =

/K, 4 = log
)
/K.
<limit value> Specifies the curve temperature limit in kelvin.
<coefficient> Specifies the curves temperature coefficient. Valid entries:

1 = negative, 2 = positive.
Remarks Configures the user curve header. The coefficient parameter will be calculated auto-
matically based on the first two curve datapoints. It is included as a parameter for
compatability with the CRVHDR? query.
Example CRVHDR 21,DT-470,00011134,2,325.0,1[term] configures User Curve 21 with a
name of DT-470, serial number of 00011134, data format of volts versus kelvin, upper
temperature limit of 325 K, and negative coefficient.
