8.5 Protecting settings from unauthorized access
The following write protection options exist in order to protect the J22 TDLAS Gas Analyzer software configuration
from unintentional modification:
• Protect access to parameters with access code
• Protect access to local operation with keypad locking → 
• Protect access to measuring device with write protection switch → 
8.5.1 Write protection through access code
By enabling user-specific access code, the parameters for the measuring device configuration are write-protected and
their values can no longer be changed through local operation.
8.5.2 Defining the access code through local display
1.
Navigate to the Define access code parameter.
2.
Define a max. 16-digit character string comprising numbers, letters and special characters as the access code.
