and press ‘ENT’.
If the command was successfully comleted ADC or measured
value is displayed in format:
‘

device address / loop number: value’. In this example the
measured by ADC value of loop

17 of device with address 2
is equal to 51. Each 0,5 seconds console automatically refreshes
given loop ADC value. By means of buttons ‘

ADC values of given device can be viewed.
The following tables contain couples of loop resistance and corresponding ADC value.
ADC value can vary from 0 to 255. Value 0 corresponds to loop open circuit, value 255
corresponds to to short circuit.
