8.5 Memorizing Optical Temperature Control Equation

Cuvette heating under optical temperature control is intended to
memorize the intensity of the light emitted from the cuvette at
each temperature and to control heating so as to match the light
intensity.
This is executed independently for each type of cuvette and
calibration data is retrieved for each cuvette. No equation is
memorized for a cuvette type used for the first time. In such an
event, click [Confirm GA optical temperature control] in the
[Instrument control] menu for the execution.
In atomization under the optical temperature control, once the
equation is memorized, atomization temperature is always kept
at a constant level (emission intensity) despite a change in
cuvette resistance.
Since the relationship has been memorized before shipment
from the factory, it needs not to be memorized frequently by user.
Memorization is required once in a few months or half-yearly
because the emission intensity received by the detector may
differ due to change of the instrument with time. Memorization
of the equation involves heating for about 2 minutes.
In this case, be sure to use the Pylon tube HR, Pylon tube C HR
or Tube HR cuvette.
For memorization, click [Memorize Opt. Temp. Cont. Equation] in
the [Instrument Control] menu.
