Coralife PH Probe

[OldSalty]

i aquired a coralife didital handheld ph probe. Anyone know how to calibrate it?. there is no model # on it nor can i find any adjustment screws. it has 3 buttons as follows. top button says hold/con, middle button says cal, bottom button says on/off. If anyone has on of these let me know.

thanks
