Model 335 Temperature Controller
BRIGT? Display Brightness Query
Input BRIGT?[term]
Returned <brightness value>[term]
Format n (refer to command for description)
CRDG? Celsius Reading Query
Input CRDG? <input>[term]
Format a
<input> A or B
Returned <temp value>[term]
Format ±nnnnnn
Remarks Also see the RDGST? query.
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.
