■ Alarm display in bar graph
When setting or occurring the alarm, it displays the status by the bar graph. It is possible
to check the alarm status. When setting alarm value, the bar LED for this alarm value
turns ON. When alarm occurs, the bar LED for this alarm value flashes.
• If alarm set value is out of bar graph scale when setting the value or in RUN mode, this
value does not display in bar graph.
Monitoring mode: setting alarm value
The bar LED for alarm setting value flashes.
When alarm set is complete, the bar LED
for this alarm value turns ON.
• The bar LED for the alarm value flashes.
■ Scale value relation
Below is relation example of input specification, high/low limit input, high/low limit
scale, bar graph display high/low limit scale, 4/20 mA transmission output scale when
using 4 to 20 mA input specification.
Refer to 'Parameter Setting' for the details about setting range and condition.

additionally adjusted by using the 'Input correction' function.
Function: Input Digital Filter
Moving average digital filter is able to stably display and output the noise from input
line and irregular signals as software.
• Display cycle is same when executing moving average digital filter.
