Lake Shore Model 330 Autotuning Temperature Controller User's Manual
ECUR
Edit or Add A Data Point In User Curve.
Input:
ECUR XX,Y.YYYYY,ZZZ.Z
Returned: Nothing
Remarks: Enter the point to be added or edited: XX = curve number from 11 to 31, Y.YYYYY = voltage,
and ZZZ.Z = temperature in kelvin. Data points in Curves 00 thru 10 cannot be edited. If the
Model 330 does not recognize either the units value or the temperature value, it assumes you
are entering a new point and places it in the proper ascending position.
Example: If the point to be edited was input as 0.19083,364.0 and should have been 0.19083,365.0,
input this command: ECUR 11,0.19083,365.0[term]. The Model 330 recognizes the
units field and replaces that data point with the new temperature value.
