What is Zero Adjustment , Span Adjustment and Linearity Adjustment

The video talks about basic terminology used widely in instrumentation and calibration field such as what is zero Adjustment , how to calculate span for the instrument, what is Span Adjustment and what is the significance of Linearity Adjustment .

Span is algebraic difference between upper and lower range values
Therefore
SPAN = URV -LRV

“Zero” is an offset adjustment. It means that if the measured value on an instrument is 2% up or down, that it just needs an offset or zero adjustment around the set point.
