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 10 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 2 curve datapoints. It is included as a parameter for com-
patability 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.
CRVHDR? Curve Header Query
Input
CRVHDR? <curve>[term]
Format nn
<curve>
Valid entries: 1–59.
Returned <name>,<SN>,<format>,<limit value>,<coefficient>[term]
Format s[15],s[10],n,+nnn.nnn,n (refer to command for description)
CRVPT Curve Data Point Command
Input
CRVPT <curve>,<index>,<units value>,<temp value>[term]
Format nn,nnn,±nnnnnn
<curve>
Specifies which curve to configure. Valid entries: 21–59.
<index> Specifies the points index in the curve. Valid entries: 1–200.
<units value>Specifies sensor units for this point to 6 digits.
<temp value>Specifies the corresponding temperature in kelvin for this

point to 6 digits.
Remarks Configures a user curve data point.
Example CRVPT 21,2,0.10191,470.000,N[term] —sets User Curve 21 second data point to
0.10191 sensor units and 470.000 K.
CRVPT? Curve Data Point Query
Input
CRVPT? <curve>,<index>[term]
Format nn,nnn
<curve>
Specifies which curve to query: 1–59.
<index> Specifies the points index in the curve: 1–200.
Returned <units value>,<temp value>[term]
