Span Error of Calibration

Span Error of Calibration

It is Important Part of the Calibration of Instrument of Standard Measurable Instrument.

How to Find out Span Error of Instrument

Formula :-

Example :- 1

Calculate the percent of span error for Ph analyzer as per the below details.

LRV = 4 pH
URV = 10 pH
Test buffer solution = 7.04 pH
Instrument indication = 7.13 pH

Solution :-

          (Actual Instrument Reading – Standard Equipment Reading)

= ______________________________________________________

                   (Upper Range Value – Lower Range Value)

Put the Value in this Formula And Given the Answer

Answer = +1.5% of Span
