10.1
Check calibration values
By checking the value pairs, possible calibration errors can already be
avoided before the entry of the calibration value pairs.
Carry out a check using the EC2342 message text:
* All TSS values within measuring range?
(see operating manual)
* At least one value pair entered?
* All TSS and SiO2 values entered?
* All TSS/SiO2 pairs in descending order?
* Pair 1 = highest TSS and SiO2 value?
Note
For examples of valid value pair data, see section 4.2.2.
The graph of the value pairs must not contain any turning point in the
required measuring range (see section 4.2.4).
