CRVDEL Curve Delete Command
Input: CRVDEL <curve>[term]
Format:
nn
<curve> Specifies a user curve to delete. Valid entries: 21
– 41.
Example: CRVDEL 21[term] – Deletes User Curve 21.
CRVHDR Curve Header Command
Input: CRVHDR <curve>, <name>, <SN>, <format>, <limit value>,
<coefficient>[term]
Format:
nn,aaaaaaaaaaaaaaa,aaaaaaaaaa,n,±nnn.nnn,n
<curve> Specifies which curve to configure. Valid entries: 21
– 41.
<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 = Ω/K,
4 = log Ω/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.
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.
