5.7 Resetting the customer parameters
It is advisable to reset the customer parameters if you want to use a device with an unknown history.
Effects of resetting:
• All customer parameters are reset to their default values.
• Customer interference echo suppression is not deleted.
• Linearisation is switched to "linear", but the table values are kept. The table can be switched
back on in the "linearisation" (04) function group in the "linearisation" (041) function.
In order to carry out the reset, enter the number "333" in the "reset" (0A3) function in the
"diagnostics" (0A) function group.

Caution!
A reset may lead to impairment of the measurement. As a rule, a basic calibration is required after
a reset.

Note!
The default values of each parameter are shown in bold in the menu overview in the appendix.
