12 Advanced Measuring Functions
12.8 Change of Limit for the Inner Pipe Diameter
It is possible to change the lower limit of the inner pipe diameter for a given transducer
type.
Press key C. Enter HotCode 071001.
12.9 Program Code
A current measurement can be protected from an inadvertent intervention by a program
code.
If a program code has been defined, it is requested when there is an intervention in the
measurement (a command or key BRK).
If a program code is active, the message PROGRAM CODE ACTIVE will be displayed for a
few seconds when a key is pressed.
To start a command, it is sufficient to enter the first three digits of the program code
(= access code).
To stop a current measurement, the complete program code has to be entered (= break
code).
The input of a program code will be interrupted with key C.
If a calculation channel has been activated, HumanMux
mode (see section 11.2.2) is selected at the beginning of
the measurement and the values of the calculation chan-
nel are displayed.
If AutoMux mode is selected, the measured values of the
measuring channels, but not of the calculation channels
will be displayed alternately.
Press key to display the calculation function.
Press key to display the measured values of the vari-
ous channels.
Enter the lower limit of the inner pipe diameter of the dis-
played transducer type. Press ENTER to select the next
transducer type.
Note! If a transducer is used below its recommended inner pipe diameter, a
measurement might be impossible.
Note! Do not forget the program code!
