Description Set the RTD parameters.
#include "SMU2060.h"
#include "USBDMMUser.h"
int DMMSetRTD(int nDmm, double ldRo)
Remarks This function sets the RTD parameters. The DMM must be in RTD measurement
function for this function to execute properly. Connect your RTD using a 4-wire
connection. ldRo sets the RTD R
o
(Ice point resistance). Since it modifies the default R
o
parameter for the selected RTD, this function must follow the selection of the basic RTD
type, using DMMSetRange.
