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". The "inhibit"
protects parameters against unintentional operations.
Step 1 Press the ON:OFF key to turn off the display.
Step 2 While pressing and holding the PRINT key and
the SAMPLE key, press the ON:OFF key to
display p5 .
Step 3 Press the
PRINT key. Then the balance displays the function switches.
Step 4 Set the switches using the following keys.
SAMPLE key To select a switch to change the parameter. The selected switch
blinks.
RE-ZERO key To change the parameter of the switch selected.
0 To inhibit changes. (Can not be used.)
1 To permit changes. (Can be used.)
PRINT key To store the new parameter and return to the weighing mode.
CAL key To cancel the 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.
1 To permit calibration using the internal mass.

0 To inhibit calibration using an external weight.
1 To permit calibration using an external weight.
Automatic self calibration
(Calibration due to changes in temperature)
0 To inhibit automatic self calibration.
1 To permit automatic self calibration.
