8. 3 Output data format
8.3.1 Data format
By changing the function settings of a scale, the following 2 format is selectable.
① 7-digit format
This is standard format.
② 6-digit format
This effective digit is 6-digit. (Effective digit of data can be 7 digit in VC
series. In this case, the smallest digit can be cut off or an error occurs if
6-digit format is set up.
＊ The setting of output data format can not be controlled from external
devices.
8.3.2 7-digit format
Consists of 15 words, including terminators ; CR = 0DH， LF＝0AH. Parity bit can
be added under this format.
