Measurement mode after the large dual LCD displays all segments briefly.
The upper display shows the measured pH or ORP value, while the lower

Annunciators at the right side of the display indicate whether the controller is
set for pH or mV measurement..
Similarly annunciators or icons at the top or left side of the display shows the

addition, error messages also guide the user in time of any faulty conditions
as indicated by “ERR” or icons flashing.
