When Alarm Latch is Enabled
Using the software tool or the message communications, setting the alarm latch to "Enabled" will latch
the alarm condition of comprehensive alarm (warning or critical).
After the occurrence of comprehensive alarm (Warning or Critical), even if the measurement value falls
below the threshold of Warning or Critical by hysteresis (10% of the threshold setting value) (upper limit
alarm) or higher (lower limit alarm), Hold (alarm latch) the state of comprehensive alarm (alarm bar and
transistor outputs 1 and 2).
The alarm latch is released for the first time by pressing the [ALM RST] key on the front of the K6CM
device.
The operation when pressing the [ALM RST] key varies depending on the push timing as follows.
 When [ALM RST] Key Is Pressed during Measuring and Monitoring
If you press the [ALM RST] key during measuring and monitoring, both the alarm bar and transistor
outputs 1 and 2 return to the comprehensive alarm state at that time.
