higher value of this coefficient results in a higher settling time,
that means a higher stability. The best result is generally obtained
by setting the filtering coefficient at a value equal to at least 10
times the value of the range parameter. Considering the example
above: 1.5*10=15. To enhance the stability, you may also
increase the filtering coefficient (values within 1 and 255 only).

What is ASY
The ASY variable allows you to control the symmetry of the
star / delta voltages (for systems without neutrals) and star
voltages (for systems with neutral). The variable is calculat-
ed as follows:
where the first formula is to be applied with delta systems,
while the minimum value calculated between the two is to
be used for the star systems.
It’s very important, as a general rule, to plug in and
extract the optional modules only when the instru-
ment is switched off.
