Default
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.
Auto
(if valid
temperature
sensor
recognized)
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
.
