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 menu item 55 "Parameter/user code". All the parameters remain visible
but can only be changed after entering the user code.The "key" symbol is shown on the display.
If the limit values are also to be locked, the "Limit code" must be set to "On" in menu item 55. Limit
values can then only be changed after entering the user code. If the limit code is set to "Off", limit
values can be changed without entering the user code. All the other parameters are locked,
however.
Hardware locking
In addition, configuration can also be locked using a connector on the rear of the device (see
drawing). This is indicated by the "padlock" symbol on the display.
To hardware-lock the measuring device, insert the jumper into position J1 in the top right-hand
corner on the rear of the device.
