● Positive and negative shifts : after positive and negative shifts of zero absolute values of upper-and-lower-limit values of span and measuring range not exceed 100% of upper limit of measuring range.
( smart type : turn down ratio 20:1, 40:1) Maximum positive shift is 500% of minimum adjusting span;
maximum negative shift is 600% of minimum adjusting span.
