Questions answered in PH/ORP manuals
Why is there no display on the controller?
Check that the power is connected and the fuse is intact; a missing power supply or blown fuse will prevent the display.
What causes the displayed numbers to jump erratically?
The electrode lead may be wet or the electrode ceramic contaminated; clean the ceramic with 0.1 M HCl or replace the electrode if needed.
