4.8 Calculated data setup

On this setup, parameters can be set for calculated data.

When two modules are installed on the instrument, the calculated data can be set for pH values

or ORP values measured by two sensors.

Select“Differential”or“Average”ontheCalculateddatasetupscreen.

Differential:Adifferencebetweenmeasurementvaluesmeasuredbyasensor1andsensor2

is an output as a calculated result.

(Diff) (valueofthesensor1)–(valueofthesensor2)

Average: The average of measurement values measured by a sensor 1 and sensor 2 is an

output as a calculated result.

(Ave) (value of the sensor 1 + value of the sensor 2) / 2

Todisplaythecalculatedresult,select“Calculated”ontheDualdisplayscreen(Section4.7.1).

(The setting on the “Individual display” has no effect.)

While displaying a calculated data, measurement value of the sensor 1 or sensor 2 can be

checkedontheeachsensor’sdisplaywithpressing

Sensor

at the lower right on the Main

display.

Pressing

returns the display to the original calculated data display.

A calculated data can be set as a process parameter on the “mA (Output)” setup screen (Section

4.3).
