Kinetics - wtw PhotoLab S12-A Operating Instructions Manual

9. Kinetics

The kinetics function enables the tracking of time-
dependent changes in concentration or absorbance (for
one selected wavelength) by repeating measurements
over an adjustable time interval (setting possibility 00:05
to 60:00 min, smallest interval 5 seconds).
The kinetic measured values are stored in the memory
in the same way as the measured values from single
measurements (older measured values are over-
written). The maximum number of measuring cycles of
a kinetic measurement is 1000 measurements
(until the memory is full of kinetic measured values). The
current measured value number appears in the header
of the display. When the memory is full, the meter aborts
the kinetic measurement. The starting values of the
kinetic are not overwritten!
The output of kinetic measured values after the termina-
tion of the measurement is performed via the menu
item, download memory.
