Sensor mV
This menu displays the mV from the electrode. It is useful for troubleshooting.
Self Test
Press
ENTER
to perform a self-test. If it says "FAIL" in the upper right hand corner, this indicates a
problem with the controller which should be returned for repair. If it passes, and you have a problem
calibrating, it is an electrode or preamp problem.
Sensor Type
Press
ENTER
to set up the controller to match the type of electrode to be used. Use the Up and Down
arrows to toggle between standard pH, antimony pH, and ORP, then press
ENTER
to make your
selection. The controller will warn you to check your set points because the units of measure have
changed.
Press any key to clear the warning messages.
