6.1.4 Security
The analyzer is fitted with an internal security switch that, in combination with the 'Configuration security' parameter settings (see
page 31), is used to prevent unauthorized access to the Configuration Level.
Two methods of configuration access protection are available:
1.
Password protection
(Factory Default)
The Configuration level can be accessed only when the correct password has been entered.
2.
Internal security switch protection
The Configuration level can be accessed only when the internal security switch is set to the 'Enabled' position.
To access the internal security switch:
1. Switch off the power supply to the analyzer and turn the two door retaining screws
