4.5.1
Allocating the current value/redox potential
The following table shows how the correct current values on the transmitter's actual value output are al-
located to the simulated redox potential on the simulator using the set pH values for the measuring range
0 to 500 mV ≙ 0 to 20 mA (zero point at 0 mV).

Testing switch and controller outputs
Once you have calibrated the transmitter, you can test the functionality of the switch and controller out-
puts. To do so, read the corresponding chapter in the operating manual for the transmitter.
