Signametrics 78
Description Return the resistance component of the last AC Caps measurement.
#include "SMU2060.h"
int DMMGetACCapsR(int nDmm, double *lpdResult)
Remarks This function retrieves the resistive component from last reading of the In Circuit (AC
based) Capacitance measurement. It performs all scaling and conversion required, and
returns the result as a 64-bit double-precision floating-point number in the location
pointed to by lpdResult. Returned result is a value in ohms. Read about In-Circuit
Capacitance Measurements section of this manual.
Parameter
Type/Description
nDmm
int Identifies the DMM. DMMs are numbered starting with zero.
lpdResult
double * Points to the location to hold the resistance value.
Return Value The return value is one of the following constants.
Value
Meaning
DMM_OKAY
DMM initialized successfully.
Negative Value
Error code
OVER_RNG
Over range occurred, implying a very high parallel resistance value.
Example double d;
int status;
status = DMMGetACCapsR(0, &d);

Description Get DMM reading rate
#include "SMU2060.h"
int DMMGetAperture(int nDmm, double *lpdAperture)
Remarks This function returns a double floating point value of the currently selected Aperture. It is
not available with the SMX2055 DMM.
Parameter
Type/Description
nDmm

Return Value Integer value version code or an error code.
Value
Meaning
Negative Value
Error code
Example
int status; double aperture;
status = DMMGetAperture(0, & aperture);
