BM series 379. Function Switch And Initialization9.1. Permit Or InhibitThe 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 switchcan select either "permit" or "inhibit". "Inhibit" protects parameters against unintentional operations.1 Press the ON:OFF key to turn off the display.2 While pressing and holding the PRINT key and the RANGE key,press the ON:OFF key to display p5 .3 Press the PRINT key. Then the balance displays the function switches.4 Specify the switches using the following keys.RANGE key........... The key to select blinking digit.RE-ZERO key........ The key to change the parameter for the selected switch.0 To inhibit changes. (Can not be used.)1 To permit changes. (Can be used.)PRINT key ............ The key to store the new parameter and return to the weighing mode.CAL key................ The key to cancel the operation ( Clr is displayed ). To return to theweighing mode, press the CAL key once again.Function table0 To inhibit changes to the function table.1 To permit changes to the function table.Calibration using the internal mass (One-touch calibration)0 To inhibit calibration using the internal mass.1 To permit calibration using the internal mass.Calibration using the external weight0 To inhibit calibration using the external weight.1 To permit calibration using the external weight.Automatic self calibration (for variation of ambient temperature)0 To inhibit automatic self calibration.1 To permit automatic self calibration.Internal mass correction0 To inhibit correction.1 To permit correction.
