Return Value The return value is one of the following constants.
Value
Meaning
DMM_OKAY
Function succeeded.
Negative Value
Error code
Example int status = DMMSetTempUnits(0, DEG_F) // set units to F

SMU2060  SMU2064 
Description Sets the polarity of the trigger input.
#include "SMU2060.h"
int DMMSetTrigPolarity(int nDmm, int iPolarity)
Remarks This function sets the external hardware and soft trigger polarity. For negative edge set
iPolarity to 0, and 1 for positive edge. The default is negative polarity. This effects the
various hardware trigger operations.
Positive Edge is imlied by a transition from 0V to a voltage over 3.5V at the Trigger
input line. Negative edge is implied by transition from a voltage over 3.5V to 0V.
Parameter
Type/Description
nDmm
int Identifies the DMM. DMMs are numbered starting with zero.
iPolarity
int Determines the polarity of the inut edge. 0 sets it to negative and 1
to positive edge.
Return Value The return value is one of the following constants.
Value
Meaning
DMM_OKAY
Function succeeded.
Negative Value
Error code
Example int status = DMMSetTrigPolarity(0, 1); //set positive edge trigger
DMMSetTrigRead
