3 Measuring and Monitoring Mechanism
3-1

Overview

The measurement makes it possible to calculate the measurement value based on the input from the
sensor. The calculation is executed inside the K6CM even in the unmeasured state before the trigger
start, and the measurement display is updated when the trigger is established. The monitoring (alarm)
captures the measured value when the trigger is established. The monitoring (alarm) involves first judg-
ing the threshold value of the Warning/Critical for each measured value, and then judging whether each
measured value is within the Warning/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". The "Comprehensive alarm" is displayed on the front LCD alarm bar of the
K6CM device and transistor output is performed (*1). Both measurement and monitoring (alarm) are
executed either always or when a trigger condition is satisfied.
*1. If the alarm latch is set to "Yes", the alarm status of the K6CM comprehensive judgment (such as alarm bar
and transistor outputs 1 and 2) is held. Pressing the [ALM RST] key on the front of the device releases the
latch. Also, the transistor output type of output 1 and output 2 can be set to Normally closed or Normally open.
As shown in the figure, it is as follows.
