Calculation of Acceptable Limits

_______% of Range (FULL SCALE) ________ Where any of these quantities are

______% of Reading(INPUT/OUTPUT) _______ given, cross multiply the values across,

______#of Digits(RESOLUTION) _______ and then add to fill the total block.

This TOTAL = ___________ value is then applied to the %READING

EXAMPLE : 930V applied, 1200 Volt Range, 8 1/2 digit display, tolerance (.015% input + .01% range + 5 digits)

.01% Range * 1200 = .12

.015% Input * 930 = .1395

8 1/2 digits 1 2 0 0.0 0 0 0 5 (NOTE : ELIMINATE #’s LEFT OF DECIMAL)

TOTAL = .25955 WHICH IS THEN APPLIED TO 930v FOR LIMITS OF 929.74045 to 930.25955
