Maximum Value and Minimum Value of Measurement value

The K6CM retains the Max./min. measurement value during measuring and monitoring period as inter-
nal data. They can be read by the software tool or by message communications.
With this function, by reading the maximum or minimum value of the measurement value for a certain
period and comparing it with another period, it is possible to detect signs of Criticality of the motor.
Also, changing the setting allows you to set the display value of the front LCD of the K6CM device to
the maximum value or the minimum value.
The software tool or message communications can be used to reset the retained Max./min. values after
monitoring by operating the "Max./min. reset" setting.
The measuring and monitoring period depends on the trigger mode. The maximum value and the mini-
mum value also operate according to each trigger mode as follows.
