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). There are five switches for the purpose of protecting
parameters. Each switch can select either "permit" or "inhibit". "Inhibit" protects parameters
against unintentional operations.

3 Press
the
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.)
key .............The key to store the new parameter and return to the weighing mode.
CAL
key.................The key to cancel current operation and return to the weighing mode.
Function table
0 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.
