Frequently asked questions

To what extent can I override the measuring range?

Within certain bounds the measuring range between, for example 4 and 20 mA can be exceeded or undercut. Normally a range from 3.8 to 20.5 mA should be able to reach the maximum output level. This is what NAMUR defines in its recommendation NE 43. Below and above these values there are voltage ranges for signalisations, typically 3.6 mA or 22 mA.
