DMMReadTotalizer
SMU2060  SMU2064 
Description Read the totalized value accumulated by the Totalizer function.
#include "SMU2060.h"
int DMMReadTotalizer(int nDmm, int * lpiTotal)
Remarks This function reads the total value accumulated by the Totalizer function. For details see
DMMStartTotalize.
Parameter
Type/Description
nDmm
int Identifies the DMM. DMMs are numbered starting with zero.
lpiTotal
int * Pointer at which the totalized accumulated value is stored.
Return Value The return value is the totalized count, or if negative one of the following constants.
Value
Meaning
Negative Value
Error code
Example
int val; int err = DMMReadTotalizer(0, &val);
DMMReadWidth
SMU2060  SMU2064 
Description Return the pulse width of the input signal.
#include "SMU2060.h"
int DMMReadWidth(int nDmm, int iPol, double *lpdWidth)
Remarks This is function requires the DMM to be in ACV measurement range appropriate for the
input signal amplitude. It makes a Positive or Negative signal width measurements,
depending on the value of iPol, placing the double-precision floating-point result in a
location pointed to by lpdWidth . The measured widths are affected by the setting of the
Threshold DAC.
