Attention: In mode 1 the output rate is dependant on the selected filter level (FL) and will be

automatically adjusted by the PC6D.

UR Set the update rate (average building) [ 2100sub11 ]

This command will define over how many measurements, from the preceeding IIR or FIR

filter, an average will be calculated. The average will be calculated over 2

samples.

Permitted values 0...7 (see table below).
