5.5 Setting a Security Code
The security codes prevent accidental or unwanted changes to program settings, displays,
and calibration. The 56 has two levels of security code to control access and use of the
instrument to different types of users.
The two levels of security are:
• All: This is the Supervisory security
level. It allows access to all menu func-
tions, including Programming, Cali-
bration, Hold and Display.
• Calibration/Hold: This is the operator
or technician level menu. It allows ac-
cess to only calibration and Hold of the
current outputs.

screen. Upon entry of the proper code, the following security screen will appear.

menu functions, including Programming, Calibration, Hold and Display.
