About the number of data on a line and the interval mode, refer to the following sections.

9.3. Number of Data on a Line

This function is useful for storing data with different contents or items at the same time, for example, ID and number of samples in a counting scale. When the number is set, <CR>s of up to the setting are converted into commas. Once the number of <CR>s is reached the setting, a new line starts.

For example, the ID, number of samples and weight are sent individually. Using this function, these three data items can be placed on one line as shown in (B).

Example data received to transmit to Excel

ID,000123<CR><LF>

QT,+00000056 PC<CR><LF>

ST,+0003.102 g<CR><LF>

(A)When the number of data on a line is 1, the ID, number of samples and weight are stored on separate lines.

(B)When the number of data on a line is 3, the ID, number of samples and weight are stored on one line.
