New Unit High ALK readings

Wondering if somebody could help me out in this forum. Just received mine today and got it all set up and the reading is 3 dkh higher with the alkatronics.

Alkatronics is 12.5
Hanna and Red Sea is 9.5

I mixed the provided 250ml bottle regent with 1000 ml of RO water. Did it by weight, 1000 ml = 33.8 oz plus 25 ml from the bottle 8.5 oz gave me 42.60z I think? bottle has a little or than 250 ml.

Calibrated Channel A twice 57 ml twice
Calibrated Channel B twice 8.5 ml twice (I did notice the .5 ml per line)

PH probe calibrate to both 7 ph and 4 ph.

It seems pretty simple put its way off. Anybody have any ideas?

have you done a test pump for A and C? not a calibration but a Test. this should output 50ml and 10ml exactly.
