D Zero tracking is a function to compensate slow drift of zero within the constant condition, and also to follow the zero point of the instrument in order to stabilize zero point. D When data variation width within the set time with Function F−08 is within range of set value set with F−07 against zero point, then the input will be compensated for zero point.
