DMMTerminate
SMU2060  SMU2064 
Description Terminate DMM operation (DLL)
#include "SMU2060.h"
int DMMTerminate(int nDmm)
Remarks Removes DMM number nDmm. This routine is used only where it is needed to terminate
one DMM and start a new one at the same nDmm location. Otherwise, it is not
recommended to use this function.
Parameter Type/Description
nDmm
int Identifies the DMM to be suspended.
Return Value The return value is one of the following constants.
Value
Meaning
TRUE
DMM Terminated
FALSE
DMM was not initialized, termination is redundant.
Example DMMTerminate(0); /* Terminate DMM # 0 */
DMMTrigger
SMU2060  SMU2064 
Description Software Trigger the DMM. Take iSamples.
#include "SMU2060.h"
int DMMTrigger(int nDmm, int iSamples)
Remarks Following reception of this function takes iSamples readings at the currently set function
and range, and stores them in an internal buffer at the currenly set Aperture and Read
Interval. No autoranging is allowed during this operation. Read Interval must be set
between 0 (default) and 65ms. Aperture must be set between 160ms and 2.5us. The
value of iSamples should be between 1 and 80 for an Aperture of 1.4ms to 160ms. It
can be set between 1 and 120 for Apertures in the range of 625us to 2.5us. The highest
Aperture allowed is 160ms. Between the times the DMMTrigger command is issued and
the time the buffer is read, no other command should be sent to the DMM, with the
exception of DMMReady function, which monitors the completion of the capture
process. When DMMReady returns TRUE, the buffer can be read one reading at a time
using DMMReadBuffer. The value of the Aperture is set using the DMMSetAperture
function, and that of the Read Interval is set using the DMMSetReadInteval.
