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