About the filter Processing
This device provides a filter function that calculates the moving average as shown below.
(1)-4 EU (Scaling)
Converts the measured signal into specified units.
CHECKPOINT
• If a message appears, follow the instructions by reducing the number of digits to be output by one,
or leaving the number of digits as is and changing the EU value.
• The Scaling operation is calculated using a ratio of the Meas. Value or EU Output Value settings.
"++++/----" is displayed when the converted value cannot be processed by MT100.
Span may be changed according to the value set for Scaling.
