SMX2040 ; SMX2042 ; SMX2044 ;

Description Get percent deviation from the reading at the time relative was activated.

#include "s m204032.h"

Remarks This function returns a d ouble floating value that is the percent deviation relative to the reading made just before the relative functio n w as activated. T his func tion is useful in quantifying measurement errors. It can be used for ba n dwidth measur ements or DC evaluation, or percent variation of a device under test over t emperature.
