About comparisons based on a reference value and tolerance
When the reference value and tolerance method is selected, thresholds are calculated as
follows:
Upper threshold = reference value
×
(100 + tolerance [%]) / 100
Lower threshold = reference value
×
(100 - tolerance [%]) / 100
Measured values are displayed as a percentage relative to the reference value, calcu -
lated as follows:
Relative value = (measured value - reference value) / reference value
×
100 [%]
