AC_zero
Description Disable AC measurement zero funciton.
#include "SMU2060.H"
#include "UseroDMM.h"
int AC_zero(int nDdmm, int bACZero )
Remarks ith bACZero FALSE, the AC zero function is disabled. If TRUE it is enabled. The
default value is TRUE. Diabeling the AC Zero funciton allows the derivation of the value
to be set as offset parameter for the selected ACV range. This function is used during
calibration.
Parameter
Type/Description
iDmm Identifies the DMM. DMMs are numbered starting with zero.
bACZero Forces the AC zero to be active or inactive. Allowed values are TRUE
of FALSE.
Return Value The return value is one of the following constants.
Value
Meaning
DMM_OKAY
Valid return.
Negative Value
Error code
Example int err;
Err = AC_zero(0, FALSE); // disable AC Zero.
DMMLoadCalFile
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.
Parameter
Type/Description
nDmm
int Identifies the DMM. DMMs are numbered starting with zero.
lpszCal
LPCSTR Points to the name of the file containing the calibration
constants for the DMM.
