Reset to the default configuration

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.
• Linearisation is switched to "linear", but the table values are kept. The table can be switched
back on in the "linearisation" (*4) function group in the "linearisation" (*40/*46) function.
In order to carry out the reset, enter "33333" in the "reset" (*A3) function in the "diagnostics"
(*A) function group.
Caution!
A reset leads to impairment of the measurement. 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.
