<- A timer stops after 120 seconds and indicates whether the calibration
was successful
If the calibration is not successful, the following à Message is displayed
Reasons for a failed calibration:
- Poor calibration (try again)
- The calibration fluid is contaminated (replace the liquid). Recalibrate
- Probe defective (replace the probe) and recalibrate.
If Ph and Rx are properly calibrated, the screens are automatically hidden
After, about 2 minutes, the lights go out and you can read the values on the screen. If the
calibration is correct, the values are as follows:
a) pH 7,0 + 0,1
b) Redox 468 + -10 mV
If the values are not within the range described above, you can repeat the calibration
using the pH and ORP keys.
Method 2: Calibration using an alternative measurement method
10 Preparation of the pool water
Make sure that the pH value of the pool water is at least
between 7.2 and 8.5 and as close as possible to 7.4
Make sure that the chlorine stabilizer content (cyanuric acid) of the pool water is between 20-
40 ppm (20-40 g/ 10 m³)
11 Set parameters
A number of parameters need to be set. Press the center button. You will see the following
