Return Value The return value is one of the following constants.
Value
Meaning
DMM_OKAY
Operation successfully completed.
Negative Value
Error code
Example double CF; int status = DMMReadCrestFactor(0, &CF);
DMMReadDutyCycle
SMU2060  SMU2064 
Description Return percent duty cycle of ACV signal.
#include "SMU2060.h"
int DMMReadDutyCycle(int nDmm, double *lpdDcy)
Remarks To use this function the DMM must be in AC measurement mode, and a valid range must
be selected. It returns percent duty cycle of the signal. It is stored as double-precision
floating-point numbers in the location pointed to by lpdDcy. The measured duty cycle is
effected by the setting of the Threshold DAC.
Parameter
Type/Description
nDmm
int Identifies the DMM. DMMs are numbered starting with zero.
lpdDcy
double * Points to the location which holds the duty cycle.
Return Value The return value is one of the following constants.
Value
Meaning
DMM_OKAY
Operation successfully completed.
Negative Value
Error code
Example
double dcy; int state; state = DMMReadDutyCycle(0, &dcy);
DMMReadSR
SM2060  SM2064 
Description Measure the value of a resistor which is in series with a capacitor.
#include "SMX2060.h"
#include "DMMUser.H"
int DMMReadSR(int nDmm, double dC, double *lpdR)
