10.4 pH2 Demand or Prime – Add acid manually or prime clear flexible PVC tubes
The 'pH2 DEMAND or PRIME' quantity can be manually adjusted from 0 - 5000 ml. The default
reading is always 100 ml. This function is useful for:
- Priming tubes after an acid drum change.
- Adding the required acid from your acid demand test.
IMPORTANT: Enter the exact amount from your test result in ml (e.g., 500 ml) and the
system automatically adds 4 times that amount, thereby allowing for the 1 : 3 ACID:
WATER mix ratio in the acid drum.
PROCEDURE To enter a required amount of acid in mL, enter the 'pH2 Demand or
Prime' menu from the 'pH Control Mode' menu explained in 10.1, using the
[+], [-] & [OK] button
