2.4.7 Special Functions
Langelier Saturation Index (Water Balance)
For calculation, the following tests are required:
- pH-value
- Temperature
- Calcium hardness
- Total alkalinity
- TDS (Total Dissolved Solids)
Run each test separately and note the results.
Calculate the Langelier Saturation index as described:
Calculation of the Langelier Saturation Index
With mode 71 (see below), it is possible to select between degree Celsius and degrees Fahrenheit.
Press [MODE], [Shift] + [7] [0] keys.
Confirm with [ ] key.
The display shows:
Enter the temperature value (T) in the range between 3 and 53 °C and
confirm with [ ] key. If °F is selected, enter the temperature value in the
range between 37 and 128 °F.
The display shows:
Enter the value for calcium hardness (CH) in the range between 50 and 1000
mg/l CaCO
3
and confirm with [ ] key.
The display shows:
Enter the value for total alkalinity (TA) in the range between 5 and 800 mg/l
CaCO
3
and confirm with [ ] key.
The display shows:
Enter the value for total dissolved solids (TDS) in the range between 0 and
6000 mg/l and confirm with [ ] key.
The display shows:
Enter the pH-value in the range between 0 and 12 and confirm with [ ] key.
