12.13 Program code
An ongoing measurement can be protected from an inadvertent intervention by means of a program code.
If a program code has been defined, it will be requested when there is an intervention in the measurement (by means of a
command or key BRK).
12.13.1 Defining a program code
A program code will remain valid as long as:
• no other valid program code is entered or
• the program code is not deactivated.
12.13.2 Intervention in the measurement
If a program code is active, the message PROGRAM CODE ACTIVE will be displayed for a few seconds when a key is
pressed.
The input of a program code is interrupted by pressing key CLR.
If key BRK is pressed:
If a command is selected:
12.13.3 Deactivation of the program code
Select Special Funct.\Program code.
Enter a program code with max. 6 digits. Press ENTER.
An error message will be displayed if a reserved number has been entered (e.g., a
HotCode for language selection).
Note! Do not forget the program code!
To stop an ongoing measurement, the complete program code has to be entered (= break
code).
Enter the program code with the keys and . Press ENTER.
If the entered program code is invalid, an error message will be displayed for a few sec-
onds.
If the entered program code is valid, the measurement will be stopped.
To execute a command, it is sufficient to enter the first three digits of the program code
(= access code).
Enter the first 3 digits of the program code with the keys and . Press ENTER.
At first, 000000 is displayed. If the program code starts with 000, ENTER can be pressed
immediately.
Select Special Funct.\Program code.
The program code is deleted by entering "------". Press ENTER.
If the character "-" is entered less than six times, this character sequence will be used as
the new program code.
