Measuring and monitoring by K6CM

What is Measuring?
After the power is turned ON, K6CM calculates measurement values every sampling period based on
the input from the sensor.
The calculation of the measurement value is executed inside the K6CM even before the trigger start,
and the measurement display is updated when the trigger is established.
This is called measuring.
What is Monitoring?
According to the trigger setting, K6CM performs threshold value judgment of the Warning/Critical level
for a measurement value, and then determines whether the measurement value is within the Warn-
ing/Critical level as an "individual alarm". Next, the OR logic is obtained for each "individual alarm" and
Normal/Warning/Critical is judged for each monitor target as the "Comprehensive alarm".
This is called monitoring. It displays the front LCD alarm bar of the K6CM device and performs transis-
tor output.
As shown in the figure, it is as follows.
