The SPECORD PLUS is shut down.
If the measurements on the SPECORD PLUS have been completed and only the analysis
of the data in the ASpect UV remains, you can switch to the simulation mode. This cuts
the connection to the device. You can switch off the device after this and exit the ASpect
UV program later.

Switching the lamps on and off
manually
If necessary, the lamps can be switched on and off manually to extend the service life of
the lamps. Observe that the lamps require some time after being lit to reach a stable en-
ergy state. Before long-term measurements, the lamps should be switched on for at
least 2 hours to keep the drift caused by the lamps are low as possible. More informa-

Carrying out a first measurement with the SPECORD PLUS
The SPECORD PLUS is operated via the ASpect UV program. The program is modular and
provides measurement parameter settings and data analysis for various applications.
The description can be found in the "ASpect UV software for UV/VIS spectrophotometers"
operating manual.
A spectral measurement in the range of 250 to 700 mm is used as an example. The
holmium oxide glass filter from the Hellma standard filter set can be used as a sample, if
necessary. Measurement is carried out with the holder for standard cells.
