The measuring parameters describe the settings of direct importance
for the measurement.
electr.id 12 ASCII characters
You can assign any name you want to the connected temperature sen-
sor. This sensor Id is then contained in the report header for measured
values.
drift 0.5...1.0...999.9 °C/min, OFF
A measuring signal which changes as a function of time is regarded as
being sufficiently constant when its drift drops below the value defined
here. This can be used as criterion for the pH/Ion Meter if a displayed
measured value is to be stored or documented by printing a report (see
print criterion and storage criterion in Section 5.2 and Section 5.3).
Please note that for a drift-controlled measured value recording this drift
parameter must not be set to '
OFF', as otherwise no result will be ex-
ported.
If this drift condition is not fulfilled then this is indicated by two constant-
ly blinking triangles in the display.
An active drift control increases the reproducibility of the measurements
as a constant condition is used to define the measured result. A smaller
value for the measuring parameter Drift requires a more stable measur-
ing signal than a larger one. The set measuring parameter is also pro-
portional to the measuring uncertainty of the measured value obtained.
method 8 ASCII characters
All parameter settings can be stored together or loaded as a method
(see Section 6.1). The name of the current method is then given here.
This field is only used for information here and cannot be edited direct-
ly.
delta measurement: ON, OFF
The delta measurement permits the display of the measured value rela-
tive to a freely selectable constant reference value:
reference -999.9...0.0...999.9 °C
