Adjustment Short-circuit reset for all range
Comparator The instrument has a sorting function. RHI/RNG/RLO output. VHI/VNG/VLO output. Total NG/OK output Compare: Absolute Tolerance ±TOL Sort: The absolute deviation of measured value and nominal value is compared to the limits of each range. Percentage tolerance %TOL Sorting: The percentage deviation of the measured value and the nominal value is compared to the limits of each range. Sequential comparison sorting: the measured value is directly compared with upper and lower limits
