Parameter Type/Description
nDmm
int Identifies the DMM. DMMs are numbered starting with zero.
iMode
int Source adjustment mode: CLOSED_LOOP or OPEN_LOOP
Return Value Integer error code.
Value
Meaning
DMM_OKAY
Operation successfully completed.
Negative Value
Error code
Example
DMMSetSourceMode(0, CLOSED_LOOP); // Select closed loop mode
DMMSetSourceRes
2060  2064 
Description Set the value of the DMM’s source resistance.
#include "SMX2060.h"

int DMMSetSourceRes(int nDmm, double ldRs)
Remarks This function sets the value of the DMM’s source impedance. This value is used by
various source and measurement function. It is normally measured by
DMMOpenTerminalCal() function. This provides an external means to calibrate some of
the measurements such as ESR (DMMReadSR()) and the Sosurce V / Measure I
function, resulting in improved accuracy. The nominal value of ldRs is about 200. It
can be set from 1 to 400. See also DMMReadSR() and the SRC_V_MSR_I function.

Type/Description
nDmm
int Identifies the DMM. DMMs are numbered starting with zero.
ldrS
double The value of the source resistance. Can be 0 to 400 (Ohms)
Return Value Integer error code.
Value
Meaning
DMM_OKAY
Operation successfully completed.
Negative Value
Error code
Positve Value
Value over 100 is a warning code
Example
DMMSetSourceRes(0, 199.0); // Set source resistance to 199 Ohms
