method.
HIGH, LOW ..... Compare against specified upper and lower thresholds (default setting
method)
REF, % ............ Compare against upper and lower thresholds internally calculated from a
specified reference value and tolerance
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 [%]
