which the measured voltage has reached this comparison value except for
±1 mV.
Input range 0 - 999 s
Default value 60 s
Min. offset potential
Minimum permitted offset voltage (voltage at pH = 7.0). This value applies
for all evaluations.

Default value -15 mV
Max. offset potential
Maximum permitted offset voltage (voltage at pH = 7.0). This value
applies for all evaluations.
Input range -999 - 999 mV
Default value 15 mV
