6 Data handling

6.1 Memory organization

Measurement results together with all relevant parameters can be stored in the
instrument's memory.

6.2 Data structure

The instrument's memory place is divided into 3 levels each containing 199 locations. The
number of measurements that can be stored into one location is not limited.
The data structure field describes the identity of the measurement (which object, block,
fuse) and where can be accessed.
In the measurement field there is information about type and number of measurements
that belong to the selected structure element (object and block and fuse).
This organization helps to handle with data in a simple and effective manner.
The main advantages of this system are:
Test results can be organized and grouped in a structured manner that reflects the

structure of typical electrical installations.
Simple browsing through structures and results.

Test reports can be created with no or little modifications after downloading results

to a PC.
