5 Demonstration tables information
5.1 General notes

The description tables contain the following information:
-
Simulated values for normal and error conditions (“Error values”).
-
Indicative test results for typical measurements.
-
Position where simulated errors
are applied in brackets under “Simulation between
contacts”

The “Error values” (simulated values, shown in error fields of tables) in the description
tables are valid only for one fault switched ON at the same time.
If more than one fault is simultaneously ON
the “Error values” are summarized.

Individual demonstration tables are recognized on the basis of information stored in
the RFID TAG (legend of errors, simulation values). The TAGs are placed in the lower
left corner of each table. The TAG information is read by the PAT Demoboard if it is
put correctly on the instrument.

The values of errors (resistances and capacitances) in the description tables are
informative only.
The actual inaccuracy is up to ±10%.

If the outputs of measuring instruments are not galvanically isolated, an additional
error of up to 10% can occur on i
nstrument’s reading.
