DMMSetFastRMS
SMU2060  SMU2064 
Description Set the DMM RMS filter response time.
#include "SMU2060.h"
int DMMSetFastRMS(int nDmm, int bFast)
Remarks This function selects between the fast and slow filter of the RMS measurement function.
The default is FALSE, or slow RMS. Setting bFast TRUE (1) selects the fast responding
filter, which provides for fast 25ms settling time, and limits the low frequency bandwidth
to 400Hz. FALSE (0) selects the slow 500ms settling time, and limits the low frequency
bandwidth to 10Hz.
Parameter
Type/Description
nDmm
int Identifies the DMM. DMMs are numbered starting with zero.
bRelative
int TRUE (1) to enter relative mode, FALSE (0) to clear mode.
Return Value The return value is one of the following constants.
Value
Meaning
DMM_OKAY
DMM mode changed successfully.
Negative Value
Error code
Example status = DMMSetFastRMS(0, TRUE); // Set to fast RMS
DMMSetFuncRange
SMU2060  SMU2064 
Description Set the DMM function and range.
#include "SMU2060.h"
#include "USBDMMUser.h"
int DMMSetFuncRange(int nDmm, int nFuncRnge)
Remarks This function provies the ability to set both, function and range in a single instruction.
Using it could save some execution time. The table of values is defined as VDC_240mV,
VAC_2400mV, etc.. The definitions are in the USBDMMUser.h file.
Parameter
Type/Description
nDmm
int Identifies the DMM. DMMs are numbered starting with zero.
nFuncRnge
int A pre-defined constant corresponding to the desired function and
range.
