Turn ON the power of the K6CM device. Depending on the "Trigger mode" and "Trigger type"
set in advance in the parameter, the state of the K6CM device while power is ON will differ as
follows.

Note 1. When an input exceeds the input range, 7 segments will blink.
2. "- - - -" is displayed even when measurement and monitoring conditions are met until the measured
value is calculated from the time of power ON.
Measurement start and end conditions are as follows.
