Measurement Type Selects a measurement type compatible with the connected sensor:
pH/ORP/Ion Conc/pION
pH Sensor Type Enabled only if Measurement Type = pH.
Select a measurement type compatible with the connected sensor:
Glass/Antimony/Custom
PV Unit Enabled only if Measurement Type = Ion Conc.
Sets the process value units.
%/ppm/ppb/µg/l/mg/l
Isopotential Pt . Isopotential point.
Enabled only if Measurement Type = pH and pH Sensor Type = Custom.
Asymmetric Pot .
Asymmetric potential.
Enabled only if Measurement Type = pH and pH Sensor Type = Custom.
Valence The ion valence determines the millivolt change per decade of concentration.
Enabled only if Measurement Type = Ion Conc.
–3/–2/–1/1/2/3
Magnitude The number of magnitudes (ranging from 1 to 3) that define the ion
concentration output.
Enabled only if Measurement Type = Ion Conc.
1/2/3
End Magnitude
The ion concentration state functions by associating an end millivolt value to an end magnitude value.
Enabled only if Measurement Type = Ion Conc.
10/100/1000
End mV The end millivolt value associated with the end magnitude value.
Enabled only if Measurement Type = Ion Conc.
Temp . Unit Temperature unit displayed and applied to all temperature parameters/values.
Not enabled if Temperature Compensation Type = Manual.
°F/°C
Temp . Comp . Type Temperature compensation type – see page 51.
Manual/Auto/Auto Solution
Note. When Auto is selected and a temperature sensor is recognized, the temperature compensation calculation
is based on the Nernst equation detailed on page 51. When Auto Solution is selected and a temperature
sensor is provided with the probe, the calculation is based on the Nernst solution coefficient equation detailed
in detailed on page 51. When Manual is enabled/selected, the value set in the Manual Temp. parameter is used
for the referenced temperature compensation.
Manual Temp . Temperature value used for compensation when Temp Comp. Type = Manual compensation mode.
Enabled only if Temperature Compensation Type = Manual.
pH Soln . Coeff . Enabled only if Measurement Type = pH and Temp. Comp. Type = Auto Solution.
mV Soln . Coeff . Enabled only if Measurement Type = pH and Temp. Comp. Type = Auto.
Temp . Sensor Type
Read-only.
