What to do if OHAUS AP110 show system errors?
Turn the power off, then turn it back on. If the error persists, have the balance serviced.
What to do if OHAUS Scales show error 8.3, hardware error caused by an internal weight signal which is too high?
Check the load on the platform which may be excessive. If the error persists, the balance must be serviced.
What does error 4.4 mean on OHAUS AP110?
Error 4.4, RS232 buffer is full, may occur if no printer or computer is connected to the interface. To clear the buffer, turn the balance off or enter the Print menu and select END.
What to do if OHAUS Scales show error 8.2, internal power on error?
Turn the power off, then turn it back on.
