SAFE.PC 
(Safe Security 
Passcode for 
Digital Setup)  
 
The SAFE.PC (Safe Passcode) allows partial access to Digital Setup (i.e. only 
non-calibration/trade critical settings can be changed). For the Safe Passcode 
to have any effect, the FULL.PC passcode must also be set. The default 
passcode setting is 000000 that allows free access. Any other number will 
enable the passcode functions and restrict access. Refer to Passcodes page 
26 and Accessing Setup page 31 for more information. 
Range 000000 to 999999 
Default: 000000 
FULL.PC  
(Full Security 
Passcode for 
Digital Setup)  
 
The FULL.PC (Full Passcode) can be set to restrict access to Full Digital 
Setup. This passcode is used to prevent unauthorised or accidental tampering 
in the instrument setup. The default passcode setting is 000000 that allows 
free access. Any other number will enable the passcode functions and restrict 
access. Refer to Passcodes page 26 and Accessing Setup page 31 for more 
information. 
Range 000000 to 999999 
Default: 000000 
It is important to note that when restricting Full access to Setup the passcode 
must not be forgotten.  
It is only possible to circumvent the passcode at the factory. 
Care must be taken when setting the Full Digital Setup Passcode to ensure 
that the instrument does not become permanently locked.

Key Locking)

and 5 represent the remaining operation keys.
