Data acquisition
Depending on the selected measuring procedure, data acquisition may
have different settings.
Meas. procedure
Single or multiple measurement
standard | multiple
Switches between standard and multiple measurement.
Meas. interval
Time interval between single measurements
0.1…9999 s | off
The measuring interval is the time pattern at which a
single measurement is triggered within the series. If a
drift-controlled measurement is recorded then this is not
accepted in the measuring point list immediately, but
only at the time at which the measure acceptance con-
ditions (drift) have been fulfilled. This can lead to an ir-
regular time pattern in the measuring point list.
If '
off' is selected the single measurements will be made
at the shortest possible time interval (<50 ms).
Meas. cycles
Number of single measurements in a series
1…1000 | inf. | max
The maximum number of single measurements is 1000.
With 'inf.' the measuring series will not end, but after
1000 measuring points have been recorded no further
values will be entered in the measuring point list. With
'max' the series is stopped after 1000 measuring points.
Start val.
Measured value at the start of the series
for MEAS_PH*
pH -20…20 | off
for MEAS_U*, MEAS_IPOL*
-2000…2000 mV | off
for MEAS_UPOL*
-200 …200 µA | off
for MEAS_T*
-170…500°C | off
If a start value is set this means that the measuring se-
ries will only be started when the defined value is ex-
ceeded in the sample solution. The direction in which
the measurements alter is irrelevant.
