CAUTION!
When starting up the device, the following points must be observed:
•
The display was set in such a way at the factory that the pointer shows "0" under operating
conditions and when the tank is empty.
•
If the displacer rod is connected to the spring system under atmospheric conditions, then a
different height may cause the pointer to show something different.
•
Do not change the factory setting of the pointer. This particularly applies at high pressures
and high temperatures.
