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.
