13.14 What are the limitations for (transducer) scaling?

Scaling can extend from a 1 million-digit resolution for 1/30 of the measuring
range to a 10-digit resolution for the entire measuring range.
Let's say that 2 mV/V is set as the measuring range. Then, the minimum scale
that can be set is 0.066 mV/V over 1 million increments, i.e. 30 million for the
full measuring range. The decimal places are contained in these figures.
Therefore, entering 50,000 for 50 kN maximum capacity will give rise to a reso­
lution of 50,000 increments.
If used as a counter or for SSI sensors, the scale can be from 20 digits for one
pulse (1:20) to 10,000 pulses per displayed digit (10,000:1).
13.15 What must I bear in mind when switching parameter
sets?
It typically takes less than 200 ms to enable a new parameter set. At very low
filter limit frequencies, you need to add the filter settling time to this. If you use
digital inputs for switching, switchover occurs when the level changes at the
input (edge).
