Dosing pump calibration

Hi guys,

I've been looking for frequently asked questions and DosingPump calibration pops up fairly frequently.
I've also been looking into it myself.....

Is there not a way to add a DosingPump Calibration menu under "Setups" like you have done for PH calibration?
Something that you can add your pump, go to the DosingPump menu.
Get a measuring beaker or whatever.
Click to start calibration.
Click when you hit 10ml.
and now the RA knows how long it takes to dose in ml?

And is there a speed selector on the RA pumps? Do you do it via pwm?
I've got a marine magic doser that is awesome because I can dose my Zeo on the slowest speed. But it sucks because after a power cut it deafaults to "Please tell me what the time is" and doesn't dose......

Thanks as always.

My code has a calibration function I setup. You need to use some extra relays (real or imaginary) to turn it on and off, etc, but it will give you calibration and allow you to dose by volume instead of time. I've been using it for a while (although I only did the calibration once). Take a look at my INO. There was another thread recently where I helped someone through this.

The RA pump does not use PWM and it is not adjustable.
