9.7 Stability detection
The stability detection is the function to judge that the weight value is stable when the
change width of display is within the stability detection data width, and at the same time
the status continues longer than the stability detection time width set before.
A result of stability detection can be displayed in the status display part on the weighing
screen, and conirmed by the external control I/O (open collector output), 2-pin method
serial interface, Standard RS-485 interface, optional BCD output (open collector output)
or optional RS232C/RS422/RS485 interface.
9.7.1
Coeicient of stability detection width (STAB. DETECTION BAND)
The coeicient of the stability detection width is set in order to set the operative
condition of stability detection.
The measuring the time width of stability detection is started after detecting the change
width of the weight display within the range of data by this setting.
The set value is input with ten keys in the range from 0.0 to 99.9 in every 0.1 d.
The coeicient turns of when the setting is [0.0].
[2.0] is set as default.
Example:
The data width of stability detection per setting value [n] is calcurated in the display
conversion as follows:
Stability detection data width = Coeicient of stability detection width (n) x Scale interval
(Division)
When the setting of the coeicient of stability detection width is [4.0], and the division is
[D = 2].
Stability detection data width = 4.0 x 2 = 8.0 d
