9. Function Switch And Initialization
9.1.
Permit Or Inhibit
The balance stores parameters that must not be changed unintentionally.
Example: Calibration data for accurate weighing, Data for adapting to the operating environment,
Control data for the RS-232C interface.
The balance is equipped with five switches for the purpose of protecting parameters. Each switch
can select either "permit" or "inhibit". "Inhibit" protects parameters against unintentional operations.
