and Calibration
Water Thermometer Calibration
If water temperature is different from temperature shown by ASIN AQUA
Home, calibrate the thermometer in the water thermometer calibration
menu.
Air Thermometer Calibration
If air temperature is different from temperature shown by ASIN AQUA Home,
calibrate the thermometer in the air thermometer calibration menu.
Testing the pH probe
If the probe meet following qualifications, 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 buffer. (example
- if you dive the probe with dry and clean tip to 7,0 pH buffer the 1 minute
response must be at least 90%)
Testing the REDOX probe
If the probe meet following qualifications, 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 buffer 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 cover free repair of
supplied probe that will have higher tolerance than above described.
pH - Buffer 7,00 #12065
Redox Buffer 475 mV #12063
