Additional external measured values
on | off (Default value: off)
If this option is enabled, then a maximum of 3 new measured values can be
taken over and saved from existing measuring commands (i.e. MEAS) which
can also be displayed in curves under the designation Extern 1…3 and used
in formulas as variables 'Command name.EX1…3'-
[New]
Opens the dialog window External measured value # in which the
parameters for the external measured value can be entered (see Chapter
5.6.3.10.2, page 859).
[Properties]
Opens the dialog window External measured value # in which the
parameters for the external measured value can be edited (see Chapter

5.6.3.3.2.9 MET pH - Measured value window
Dialog window: Method ▶ MET pH ▶ Properties... ▶ Potentiometric evalua-
tion ▶ Evaluation with measured value window (pH) ▶ [New]/[Proper-
ties] ▶ Measured value window#
Measured value windows are regions on the measured value axis for which
different parameters for potentiometric evaluation can be defined. Only
those endpoints which lie within these windows and additionally meet the
parameters defined for each window will be recognized. Only one endpoint
will be recognized per window.
Lower limit pH
Lower limit for the measured value window.
Range -20.000 ... 20.000
Default value -20.000
Upper limit pH
Upper limit for the measured value window.
Range -20.000 ... 20.000
Default value 20.000
EP criterion pH
Criterion for the recognition of endpoints. Endpoints whose discovered ERC
value is smaller than the value entered here will not be recognized.
