Procedure to calibrate the dilution flow rate:
1. Place a container, accurately graduated and with

DILUTE...60 SEC TO FINISH. The 60-second timer

counter reaches zero, the display will changes to
DILUTE OZ/M, along with a number.
6. Measure the amount of water in the container and
using the (-) and (+) pads, adjust the amount of
the display to match the amount in the container.
Then press DONE.
