PRESET TARE (SUBTRACTIVE TARE DEVICE)

It is possible to set, through the communication interface, a preset tare value to be
subtracted from the display value, provided that the



≤



condition is

verified.

In case of BASE program, to delete a preset tare and return to gross weight display keep the

NET/GROSS input (if any) closed for 3 seconds.

IF A PRESET TARE IS ENTERED, IT’S STILL POSSIBLE TO ACCESS THE SEMI-

AUTOMATIC TARE (NET) FUNCTION. THE TWO DIFFERENT TYPES OF TARE ARE

ADDED.

ALL THE SEMI-AUTOMATIC TARE (NET) AND PRESET TARE FUNCTIONS WILL BE
LOST WHEN THE INSTRUMENT IS TURNED OFF.

COMMUNICATION INTERFACE

WRITING

READING



Write the value in W1.



Send command 88 to CMDR.



Send command 87 to CMDR.



Read the value in R1.

To activate the preset tare, send command 130 to CMDR.

To deactivate the preset tare, send command 9 to CMDR.

SEMI-AUTOMATIC ZERO (WEIGHT ZERO-SETTING FOR SMALL VARIATIONS)

Close the SEMI-AUTOMATIC ZERO input (only for BASE program) or carry out the operation via the

communication interface, the weight is set to zero.
This function is only allowed if the weight is lower than the



value

(see section

RESETTABLE WEIGHT SETTING FOR SMALL WEIGHT CHANGES

), otherwise the alarm



is activated and the weight is not set to zero.

THE ZERO-SETTING IS LOST UPON INSTRUMENT POWER-OFF.

COMMUNICATION INTERFACE

To reset the weight, send command 6060 to CMDR.
