Redundancy
Use this function to monitor two or three sensors with redundant measurements. The
arithmetic average of the two closest measured values is calculated and output as the
redundancy value.
rH value
To calculate the rH value, a pH sensor and an ORP sensor must be connected. It is irrelevant
whether you are using a pH glass sensor, an ISFET sensor or the pH electrode of an ISE sensor.

The options depend on the
sensors connected
You can select different types of sensor that output the
same measured value.
Example for temperature redundancy:
You have a pH sensor and an oxygen sensor at inputs 1
and 2. Select both as "Y1" and "Y2". For "Measured value"
select the temperature.
