7.5. Other Functions

7.5.1.Re-Zero Operation

Performing the function, a gross display is zeroed and an current weighing value is used as a standard point.

The operation of the function can perform form the front key, the input terminal of the I/O and command input.

The adjustable range is based on the zero calibration and Zero range [genf- 6] of the function list. The range is displayed in the unit of percentage of the weighing capacity.

The re-zero data is stored in the memory without power supply.

Resetting the re-zero data, use the I/O terminal or the F1 ~ F4 key that is set to Zero clear [1n f-nn] [2].

nn: terminal number of I/O.

Caution

When the internal A/D converter is out of range, the re-zero operation be not performed and the error code ZR.ERR is displayed.

Concerning Parameters of the Function
