Water thermometer calibration
If water temperature is diff erent from temperature shown by ASIN AQUA Home,
calibrate the thermometer in the water thermometer calibration menu.
Probe testing
Testing the pH probe
If the probe meet following qualifi cations, it can be used in the system and it is
functional:
Probe has no visible mechanical damage.
Measured pH value is in tol/- 1,0 (example - water pH is 7,2 and probe
is measuring 7,9 - the tolerance is 0,7 so lower than 1,0 - the probe is OK)
Probe response to positive or negative changes in water or buff er.
Example : if you dive the probe with dry and clean tip to 7,0 pH buff er the
1 minute response must be at least 90%
Testing the REDOX probe
If the probe meet following qualifi cations, it can be used in the system and it is
functional:
Probe has no visible mechanical damage.
The redox probe naturally ages so its sensitivity but it should never exceed the
limit tolerance -12% At the buff er test 475 mV it should not measure less than
420 mV.
Probe response to positive or negative changes in the water free chlorine
concentration.
There is no manufacturer of pH and REDOX probes that cover its
products with warranty. ASEKO has decided to cover supplied probes to
its clients by two year warranty period that covers free repair of supplied
probe that will have higher tolerance than above described.
CLF probe test
The Aseko free chlorine probe should have an output signal of at least
20 mV at chlorine concentration 0.8 mg / liter. If the signal is lower, the probe
must be sent for inspection. If the probe has a suffi cient signal, it is good
to perform a test with clean water (the water must be allowed to stand for
24 hours). In pure non-chlorinated water, the signal must be less than 20 mV.
Otherwise, the probe must be sent for inspection.
pH - Buff er 7,00 #12065
