No measured value
9.90 V < U < 10 V
The current (I) or voltage (U) can be calculated for a given ISO contamination
class as follows:
I = 4.8 mA + ISO code x (19.2 mA - 4.8 mA) / 24.28
U = 2.4 V + ISO Code x (9.6 V - 2.4 V) / 24.28
The ISO contamination class can be calculated for a given current I or voltage U
as follows:
ISO code = (I - 4.8 mA) x (24.28 / 14.4 mA)
ISO code = (U - 2.4 V) x (24.28 / 7.2 V)
ISO 2 / ISO 5 / ISO 15
The ISO x setting enables the value of a class to be continuously output via the
analog output.
