Flashing 0.00000 indicates either the weigh pan is not seated right or the weigh cell is damaged.   Unplug the power, remove the weighing pan with the special forceps in the control unit.    Wait about 30 seconds, install the pan then plug in.   If the balance is still flashing 0.00000 it is the weigh cell.    Service parts are being discontinued this year.    You will want to contact the service group at 800-638-8537 Press 1   ASAP.   If you wait, the part you need may be forever discontinued.

The Flashing 000.000 means the software is attempting to read the weighing cell outout put and it is too unstable.  If the micro balance is in a location where it has been working properly and the weighing opan is in place and empty and the draft shield glass is closed the balance will need serviced.  The weigh bridge will need to be disassembled and repaired.
