Calibration
The spectrophotometer performs a self-test each time it starts to check the basic calibration.
The basic calibration or zero calibration as well as the calibration of the nephelometric
turbidity measurement can be performed manually, if required, via the calibration menu.

6.4.1
Zero calibration
Press the
icon to open the window for the zero calibration of the instrument. Start the
calibration process by confirming with
. The instrument first takes an air measurement
and then asks for the insertion of the calibration cuvette. Place the supplied and clean
calibration cuvette in the cuvette slot; the calibration will continue automatically.
When calibration is complete, the date of calibration is stored in the device and displayed the
next time the calibration process is activated.
6.4.2
Turbidity calibration
Press the
icon to open the window for the turbidity calibration of the instrument (see
Figure 79). Select the range to be calibrated. The turbidity standards you use can be entered
in the list box on the left. The predefined standards can be deleted and replaced with the
desired values. Start the calibration process by confirming with
. The instrument will scan
the series of standards after insertion and start the respective measurement automatically.
When calibration is complete, the date of calibration is stored in the device and displayed the
next time the calibration process is activated.
Note: Turbidity standards for the calibration of the NANOTURB Sensitive range can be
purchased from GLS chemicals (US).
