P99: dcba Access lock by secret code
The purpose of this feature is to provide protection against accidental programming
or intentional reprogramming of parameters by a person not entitled to do so. The
secret code can be any value other than
0000
. Setting a secret code will
automatically be activated when the NUS-7 is returned to the Measurement Mode.
In order to program locked device the secret code should be entered first in
P99.
Thus for entering a new code or erasing the old one the knowledge of the previous
code is necessary.
