Return Value The return value is one of the following constants.
Value
Meaning
DMM_OKAY
DMM initialized successfully.
Negative Value
Error code
DMM_E_FUNC
Invalid DMM function.
Example status = DMMSetFuncRange(0, VDC_3V);
DMMSetFunction
SMU2060 SMU2064
Description Set the DMM function.
#include "SMU2060.h"
#include "USBDMMUser.h"
int DMMSetFunction(int nDmm, int nFunc)
Remarks This function sets the function used by the DMM. The USBDMMUser.h file contains a
table of values defined as VDC, VAC, IAC, IDC, OHMS4W, OHMS2W etc... Not all
functions are available for all DMM types. USBDMMUser.h lists the specific function
values.
Parameter
Type/Description
nDmm
int Identifies the DMM. DMMs are numbered starting with zero.
nFunc
int A pre-defined constant corresponding to the desired function.
Return Value The return value is one of the following constants.
Value
Meaning
DMM_OKAY
DMM initialized successfully.
Negative Value
Error code
DMM_E_FUNC
Invalid DMM function.
Example status = DMMSetFunction(0, INDUCTANCE);
DMMSetInductFreq
SMU2060 SMU2064
Description Set the frequency of the Inductance Source.
#include "SMU2060.h"
int DMMSetInductFreq(int nDmm, double lpdFreq)
Remarks This function sets the frequency of the Inductance measurement source. The value of the
frequency should be between 20 Hz and 100kHz. This function overrides the default
frequency for each of the inductance ranges. Therefore, setting a new Inductance
