5 MEASUREMENT

5.1 Display in Measurement mode

When the controller is initially powered on, it automatically enters into the

Measurement mode after the large dual LCD displays all segments briefly.

The upper display shows the measured pH or ORP value, while the lower

display shows either the temperature value if the controller is set for pH

measurement or “OrP” if it is set for ORP measurement.

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

current status of controller, e.g. “MEAS”, “SETUP”, “CAL”, “READY”, etc. In

addition, error messages also guide the user in time of any faulty conditions

as indicated by “ERR” or icons flashing.
