Menu Button>IDC Setup>Flow Calibration
When utilizing the IDC to dispense a solution, you must
determine how long your pump needs to be on to provide
a given volume of solution. Since pump efficiency, solution
strength and viscosity, tubing diameter, and many other factors
play a role in how long your pump should run, the DL122 is
equipped with a flow calibration feature.
1) Press Menu button, scroll down to **IDC Setup**, and press
SELECT.
2) Place cursor beside “Flow Calibration” and press SELECT.
3) Be sure the cursor is beside START. Using a container of
appropriate size (or one marked with an appropriate fill level),
place the tube from the pump into the container and begin
filling the container by pressing SELECT. The display will serve
as a stopwatch, recording minutes and seconds (00:00).
4) Scroll the cursor down to STOP and when the solution
reaches the fill mark, press SELECT.
5) Write down this number and plug it into the IDC Session
Time screen.
