• To set the range within which the proportional dosing occurs

(delta), press DIAG. The display will show the last diag-

nostic mode and the right-most numerical digit will blink.

0.5, 0.6, 0.7, 0.8, 0.9, 1.0, 1.5, 2.0, will scroll.

Note If the analyzer has been reset or turned on, “0.1” is the de-

fault delta.

• Store the desired delta, e.g. 0.5, pressing DIAG when the

desired value appears.

• When dosing is active, the DOSE

LED turns on and the corresponding

relays closes.

Note If the measured concentration is lower than the delta, the

dosing will be continuous until the next measurement is taken.
