Good and bad counters
The good and bad counters are used to count the analysis results. They are displayed in the info
screen.
Programming: Menu > Info
Exceeding the limit value increases the bad meter, and falling below the limit value increases the
good meter. This counter can be used to assess the function of a softening system. The number of
bad measurements should be significantly smaller than the number of good measurements. The
counters can be reset in the menu.

Calibrating the unit
The unit is calibrated at the factory at a room temperature of 20 °C. When operating in very warm
or cold locations, we recommend calibrating the unit during commissioning.
To calibrate the unit, proceed as follows:
•
Carry out an analysis with the device. The p-value of the sample must be within the
measuring range of the reagent used. A measured value such as < 0.2 mmol/l cannot be
used.
•
Analyse the water in the laboratory in parallel.
•
Calculate the correction factor for the analyser using the following formula:
𝐾𝑜𝑟𝑟𝑒𝑘𝑡𝑢𝑟𝑓𝑎𝑘𝑡𝑜𝑟 =
𝑀𝑒𝑠𝑠𝑤𝑒𝑟𝑡
𝐿𝑎𝑏𝑜𝑟
𝐴𝑛𝑧𝑒𝑖𝑔𝑒𝑤𝑒𝑟𝑡
∙ 100 %
•
Set the correction factor in the unit under the specified path.
(Programming: Menu > Settings > Analysis > Calibration factor)
Example calculation:
Measured value
Labor
= 2 mmol/l
Display value from the SYCON display = 1.8 mmol/l
𝐾𝑜𝑟𝑟𝑒𝑘𝑡𝑢𝑟𝑓𝑎𝑘𝑡𝑜𝑟 =
2 𝑚𝑚𝑜𝑙/𝑙
1,8 𝑚𝑚𝑜𝑙/𝑙
∙ 100 %
𝐾𝑜𝑟𝑟𝑒𝑘𝑡𝑢𝑟𝑓𝑎𝑘𝑡𝑜𝑟 = 111,1 %
111.1 % rounded =>
correction factor = 111 %
The entry is only made with whole numbers, therefore round down/up and enter the correction
factor in the input mask on the unit.
