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%]

When enabled, the actual readings are shown in primary display and the
percentage’s result is shown in secondary display.
• The secondary display shows OL when readings exceed the maximum
display of 999.99%.
• When autoranging is enabled, this operation will be used to lock the
current range.
