2.9.3 Free User Memory Space

These registers can be used to store any customer specific information in the sensor. There are different registers which can be read by everybody, but only specific operators can write them.

Figure 2.9.3.1: Definition of registers containing user information.

An important register is 1600, as it is the description of the measuring point. The information of this register is displayed on the ARC View Handheld in order to identify individual sensors.

Attention:

The Free User Memory Space is located in a memory which allows in total max 10’000 write operations.
