5.3.3 Disabling the programming mode
User code
The configuration can be protected against unintentional access by means of a four-digit code.
This code is defined in the submenu "Parameter/User Code". All the parameters remain visible
on the display but the "key" symbol is shown on the display. If you then want to change a
parameter, you first have to set the valid user code.
Hardware locking
In addition, configuration can also be locked using a connector on the rear of RIA452 (see
drawing). This is indicated by the "padlock" symbol on the display.
To hardware-lock the measuring instrument, insert the jumper into position J1 in the top
right-hand corner on the rear of the instrument.

Hardware locking has no effect on the PC operating software Readwin
