Teejet 844 rate issue

[Surgery]

New to me sprayer , put in some different nozzles to what came with it , been out and in auto mode it won’t get up to the right pressure , clean water on a field and worked out it was about 15l a hec out , i have entered the nozzles into the box along with the litres per hec , am I missing something? Thanks

Have you tried other nozzles that are giving correct rate? Not something like specific gravity been messed with?

Have you measured out 100 m and calibrated it ? I’ve recently had same issue with a new to me sprayer . Jug test and enter readings .
My old sprayer was so simple and what ever rate you entered it would spray at as it read the flow . New one is pressure rated so needs the nozzle selected to be entered into to computer preferably with the jug test reading and because I was using the lilac nozzles which are in between blue and yellow I had to select one with no prefix which I think are on the left of the options on the nozzle settings.

I think I have it about sorted now but for some reason it won’t let me spray above 4.1 bar which most of the time is fine but on a really still evening when wanting to get home I can see this is going to be a problem.
