Setup 1 (pH / Redox)
In the SETUP 1 function group, change the settings for the measuring mode and the sensor.
All the settings in this menu are made during initial commissioning. However, you can change the
settings at any time.
!
Note!
An error message (E010) is output if the temperature sensor is defective. Measuring continues at a
process temperature of 25 C (77 °F).

1 ... 60
Measured value damping causes averaging
over the number of individual measured
values entered. This is used, for example, to
stabilise the display if the measurement is
unstable.
There is no damping if “1” is entered.
