SMU2060  SMU2064 
Description Reload calibration record from file.
#include "SMU2060.h"
int DMMLoadCalFile(int nDmm, LPCSTR lpszCal)
Remarks This function provides the capability to reload the calibration record. This is useful in
making limited calibration adjustments, and verifying them. By having a copy of the
original calibration file ‘SM60CAL.DAT’ open with an editor, modifying calibration
parameters and then reloading using DMMLoadCalFile, one can instantly verify the
corrections made. Make sure the ‘SM60CAL.DAT’ file itself is not altered since that
will void the calibration.
