How do i calibrate a Pinpoint PH monitor

[janey]

i have the old verison , in other words not the one with Built-in calibration.

I have the fluids 7,0 and 10.0. i went the the american marine site but they only have user guide for the new ph monitors.


Thanks

Rinse your probe and then put it into the fluid, start with the 7.0. You need a very small screwdriver like the kind for eyeglasses. Turn the screwdriver until your monitor says 7.0. Rinse the probe and then do the same for the 10.0. Then go back and check again a couple of times until it seems stable.
