4.3.5 Measuring input connections

4.3.5.1 The device has 10 inputs
Tab. 6: The supported sensors are defined as follows (pH):
pH value (input PI1 or PI2)
(*): The customer's scale can be defined between -1 ... 15 pH.
Tab. 7: The supported sensors are defined as follows (ORP):
ORP value (input PI1 or PI2)
(*): The customer's scale can be defined between -1000 ... 1000 mV.
