DMMReadMedian. Artison SMX2040, S-LCR-DM, SMX2042, SMX2044

Value Meaning

TRUE Measurement was read into *lpdRead

FALSE No measurement is available

Communication timeout. No reading available within 9s. TIMEOU T

OVERR UN Communication overrun. C PU did not keep up with DMM transmission.

Other N egative Value Error code .

Example R eadin g[150];

DMMBurstRead(0, 4, 150); // 4 settel., 150 samples for(i=0 ; i < 150 ; i++) // read 150 measurements while( DMMReadMeasurement(0 , Reading[i]) == FALSE );

// wa it for a ll measur ements to be ready, and read them.

Des cription

Remarks

Return ACV sign al’s Median value.

#include "sm204032.h"

int DMMReadMedian(int nDmm, double FAR *lpdResult)

This is a Secondary funct ion and the DMM must be in ACV measurement function, and a valid range must be set. A double-precision floating-point Median voltage result is stored in the location pointed to by lpdResult. This measurement is a composite function which utilizes several sub functions, and could take over 10 seconds to perform . See the

Median measurement section of the manual for more detail.

Parame ter Type/Description

nDmm int Identifies the DMM. DMMs are numbered starting with zero.

Return Value lpdResult double FAR * Po ints to the location to hold the median voltage.

The return value is one of the following constants.

Value Meaning

DMM_OKAY Operation successfully completed.

Negati ve Value Error code

Example double Medi an; int status = DMMRead Median(0, &Median);
