Printer Interface (Optional):
The Micro 4000 is capable of driving most standard RS232C serial printers. Data such as the "Date",
"Batch No", and "Consecutive No" can be selected to be printed or not in the spec settings.
There are three modes of operation that can be selected. (spec 11 and spec 12).
Mode 1: (spec 11=off, spec 12=off)
Data is only printed when the weight is stable and the "Print" key is pressed. Only one ticket is allowed per
weighing , the displayed weight must return to within 2 divisions of zero to reset print cycle.
Mode 2: (spec 11=on, spec 12=off)
Data is automatically printed when a stable weight is detected. Once a ticket has been printed the displayed
weight must return to within 2 divisions of zero to reset the Autoprint cycle.
Mode 3: (spec 11=off, spec 12=on)
Data is printed on removal of weight. (last stable weight detected). The last stable weight is printed when
the displayed weight returns to within 20 divisions of zero.
Presetting of the consecutive ticket No:
The consecutive ticket number can only be preset in the service mode of the Micro 4000. After entering the
service mode of the Micro 4000 and with the display showing "CALI" press the "9" key, the display will
show " 0". Enter the starting number of the consecutive ticket number and press the "ENTER" key, the
display will now revert to "CALI". The "CLEAR" key can now be pressed to exit the service mode if required.
Entering the date:
With the Micro 4000 in normal weighing mode, use the "MODE" key to scroll the display until the display
shows "date", press the "ENTER" key. The display will now flash "_____0". Enter in the date in the following
format (DD-MM-YY) and press the "ENTER" key, the Micro 4000 will now revert back to normal weighing
mode.
Entering a batch number:
With the Micro 4000 in normal weighing mode, use the "MODE" key to scroll the display until the display
shows "batch", press the "ENTER" key. The display will now flash "_____0". Enter in the batch number
(max 6 digits) and press the "ENTER" key, the Micro 4000 will now revert back to normal weighing mode.
Please note:
The date and batch number are held in ram and are reset to zero if the Micro 4000 is switched off.
