2.10 Write EU Filter Parameter

A software filter stage can be configured individually for each channel using the v command
with coefficient index number 52 hex to write the n value (max = 100) for filtering EU data
(EU_delivered = EU_old + EU_new/n - EU_old/n). The factory default value is n = 1 (filter turned
off):

n values greater than 15 – 20 will slow down the step response
below what is normally used for thermocouples. Values greater
than 10 should be evaluated on a case by case basis. EU values
are returned 10 times / second regardless of filter n value.
