Initialisation and Software upgrade

2.5.1 Initialisation
At the time of delivery, all memory values of the AVS 470 Viscosity Measuring Unit are set to starting values
(so-called default values). If it should prove necessary to restore this delivery status at any time, this can be
achieved in the form of a so-called initialisation. This process is triggered by simultaneously pressing the "Up
↑ " and "Down ↓ "key for at least 2 seconds as shown in figure 5 after switching the device off and on again,
initialisation is completed.
2.5.2 Software upgrade
The software of the AVS 470 Viscosity Measuring Unit can be upgraded, but such an upgrade has to be
done by specially trained service personnel. If such an upgrade should become necessary, please contact
Schott Instruments (address can be found at the end of the present operating instructions) to take the
required action.
