Averaged spectra
The number of spectra that are acquired and averaged.
Input range 1 - 10,000
Default value 10
Smoothing
Number of neighboring pixels with which the light intensity of each mea-
surement pixel is determined.
Input range 0 - 100 pixels
Default value 0 pixels
Tab for the 089 Photometer
Blank value
Value by which the measured quantity (absorbance) is corrected. Here an
expression can also be entered through the formula editor (e.g. xx.EME
from other measuring command) by which every measured absorbance
value can then be corrected.
Input range -1E+12 - 1E+12 (max. 10 digits)
Default value 0.0
Entry 1 - 10 characters
Selection mol/L | mmol/L | µmol/L | g/L | mg/L | µg/L |
mg/mL | µg/mL | ppm | % | mEq/L
Default value ppm
Measurement
Two types of measurement can be selected from, Measurement with
drift control or Measurement without drift control.
Selection Measurement with drift control | Measure-
ment without drift control
Default value Measurement with drift control
Measurement with drift control
The measurement is carried out drift-controlled if this option is
selected. The measurement is canceled as soon as the defined Signal
drift or the Stop measured value is reached or the defined Max.
waiting time has expired. The corresponding parameters are not visi-
ble if this option is disabled.
Measurement without drift control
The measurement is carried out without drift-control if this option is
selected. Measurement is continued for as long as one of the two stop
criteria Measuring time or Stop measured value is fulfilled. The
corresponding parameters are not visible if this option is disabled.
