Activating the BPI Mode

In order to use CAS programs with the MC1 server or a personal computer,
the scale must be set to the BPI mode.
Disconnect the AC adapter from the scale and open the display unit by
removing the 4 screws at the back.
Carefully pull the front panel with the main PCB far enough away from the
rear panel to access the BPI switch (see illustration at left).
Reconnect the AC adapter and switch on the scale by pressing e.
Once 0.0g is displayed, move the BPI switch to the right.
The segment check is now displayed periodically. Wait until the segment
check has lit up at least 3 times; the scale is now in the BPI mode.
Move the switch back to the original position; the scale now shows the
normal weighing display.
Close the display unit.
You can now operate the scale in conjunction with the Sartorius MC1 server
in the BPI mode.
After working in the BPI mode, make sure to set the write-protect again (with
the Sartorius MC1 server: "close"), so that the QC scale returns to the
standard data output protocol (SBI mode).
Otherwise you will not be able to transfer data to a peripheral device; if
you press the print key, the error code "Err30" will be displayed.
This function switch has no effect on service operations, but you need to
make sure that it is always in the correct position, i.e., set to the left (see
illustration).
