6.6 Locking/unlocking
After all parameters have been entered, the manufacturer's-specific parameters can be
locked.
• via the keys +Z, –Z, +S and –S or
• via the parameter "Security Looking" by entering a three digit code ≠ 130.
(130 is the code for unlocking the parameters)
This protects the measuring point from accidental and unauthorised entries.
