Percentage (%)
This operation allows you to transfer the measurement value with a proportional
percentage display. You can set the upper limit (HI) and lower limit (LO) to any
value between 0 and ±100% of the highest range for the present function.
The percentage operation calculates and display the measurement value using
the equation below:
Percentage (%) = [Measurement value – LO/(HI-LO)] x 100%]
When the HI limit is equal to LO limit, the percentage operation will use the
equation as below:
Percentage (%) = [(Measurement value – HI)/HI] x 100%]
