Errors In Redox - swim-tec CL2 Deluxe WiFi 1,6 l/h Bedienungsanleitung

pH 7
All values agree. Device is fine. Possible causes:
Incorrect manual measurement

Outdated buffer solution

The value in the measuring cell deviates. Possible causes:
 Hydraulics (flow, filter, fresh water, bacteria in the suction pipe, etc.)
Glass break of a sensor

 Electrical influence of measuring values / interference from other components
In the event of minor buffer solution deviations (e.g. pH 6.8 and pH 3.8) calibrate the
sensor.

[?] In the buffer solution Rx 475 mV, the electrode shows a value of <425 mV.
[1] Check the temperature dependency of the buffer solution
30° C = 480 mV 25° C = 475 mV
For a buffer solution temperature of 10° C, the value 410 mV is just about OK.
[2] Buffer solution too old (more than 1 year)
[3] Replace Rx sensor if necessary. All valuesagree. Device is fine. Possible causes:
475 mV
Incorrect manual measurement
