SECURITY AND SETTING PASSWORDS

4.4.1 

Setting Security Codes

The 

security  code

  function  enables  a  security  code  to 

be set to lock the instrument settings and measurement 
mode  settings.  The  security  code  is  not  specific  to  the 
user  ID  but  is  designed  to  enable  an  administrator  to 
control  either  the  instrument  or  protocols.  The  security 
code menu is accessed through the instrument settings 
menu.

In the instrument settings menu press the key adjacent 
to the 

security code

 icon. Using the keys at the bottom 

of the screen select the digit to be changed. Use the keys 
adjacent to the 

arrow

 icons to increase or decrease the 

selected number. Once the preferred code has been set 
press the key adjacent to the

 tick

 icon to save the security 

code. 

4.4.2 

Settings lock 

The  settings  lock  function  enables  the  instrument  and  measurement  mode  settings  to  be  locked  to 
prevent any changes to the measurement parameters or instrument settings. The only exceptions to this 
are that the user ID and contrast can be changed when the settings lock is active. 

The  settings  lock  function  is  accessed  through  the 
instrument settings menu by pressing the key adjacent to 
the 

open padlock 

icon. One press will lock the settings 

instantly. To unlock the settings press the key again. This 
will open the security code menu as detailed in section 
4.4.1. The previously set security code must be entered 
to unlock the settings. When the settings lock is active 
methods can still be opened, deleted and saved but the 
method parameters cannot be changed.

To  enter  the  security  code  use  the  keys  at  the  bottom 
of the screen to select the digit to be changed. Use the 
keys adjacent to the 

arrow

 icons to increase or decrease 

the selected number. Once the correct security code has 
been entered press the key adjacent to the 

tick

 icon. The 

settings are now unlocked.

If  the  settings  are  locked  before  the  security  code  has 
been set a default code of 660 will unlock the settings.

4.4.3 

Method Lock

 

When the 

method lock

 is active the method selection 

menu is disabled in all the measurement modes therefore 
methods cannot be opened, deleted or saved. However 
the  measurement  parameters  of  the  currently  loaded 
method  can  be  changed.  The  method  lock  function 
is  accessed  through  the  instrument  settings  menu  by 
pressing the key adjacent to the 

method

 

lock

 icon.
