Data Comparison between
Channels
This function can be used to compare the temperature values between the
two inputs (inputs 0 to 1) to monitor the relative temperature difference. A
threshold value can be set to detect an excessive temperature difference for
preventative maintenance in devices in which the temperature difference may
cause or indicate a problem.
The comparison result and over-threshold status can be read in the Mainte-
nance Information Window.
Note 1. The comparison operation can be performed only on the data set as tem-
perature data.
2. If the peak value or bottom value is selected as the temperature data, the
processed peak or bottom value will be used in the comparison operation
and not the actual temperature input value.
