Hi Guys,
I purchased a Jecod DP-3 doser from a fellow aquarist who sold it to me brand new. I set it up in my office to test it before it goes onto my tank.
I calibrated P1, 2 times just to make sure 100ml was dosed on the exact number of revolutions and is spot on at 211.
Pump 2 on the other hand gave me 4 different numbers of revolutions to get to 100mls. It is off by as much as 10 revolutions. Eventually set it on the fourth try as the value was one revolution off from the second try.
Pump 3 was 2 revolutions difference so I let it be and set it.
I put it down to possible reading error. I will do more stringent testing with a kitchen scale.
I set up a dosing programme to dose 3mls 4 times a day, but on checking the output its way more than 3mls more like 4.5mls.
Anyone had any issues like this. So far the output from pump 1 and 2 looks similar in quantity. Pump 3 looks closer to 5ml. I'm pouring the output into a 3ml syringe and will go get a 10ml medicine measure shortly.
I'm not overly concerned as long as 2 pumps dose the exact amount and wont be using pump 3 anytime soon as I'll be dosing mag manually for now.
As I cant return it, does anyone have any ideas on how to calibrate it so at least I get the same dosage on at least 2 heads. Anyone has had any similar issues.
Thanks
