What does 'Communications error' mean on A&D HR-250AZ, and how to fix it?
A 'Communications error' on your A&D Scales indicates a protocol error occurred in communications. To resolve this, confirm the format, baud rate, and parity.
What to do if A&D HR-250AZ display other errors?
If the errors described above cannot be resolved or other errors are displayed, contact the local A&D dealer.
What does 'Parameter setting error' mean on A&D Scales, and how to correct it?
A 'Parameter setting error' on your A&D Scales means the received data exceeds the range the balance accepts. Confirm the parameter range of the command.
What does 'Format error' mean on A&D HR-250AZ Scales, and how to resolve it?
A 'Format error' on your A&D Scales indicates that a command includes incorrect data. To fix this, confirm the command being used.
What does 'Excess characters error' mean on A&D HR-250AZ Scales, and how to resolve it?
An 'Excess characters error' on your A&D Scales means the balance received too many characters in a command. Review and confirm the command being sent.
What does 'Timeout error' mean on A&D Scales, and how can I fix it?
A 'Timeout error' on A&D Scales means that the balance didn't receive the next character of a command within one second. Verify the communication setup.
What does 'Not ready' mean on A&D HR-250AZ Scales, and how to fix it?
If your A&D Scales display 'Not ready', it means a received command cannot be processed. Adjust the delay time to transmit a command.
What does 'Undefined command error' mean on A&D HR-250AZ, and how do I fix it?
An 'Undefined command error' on your A&D Scales means an undefined command was received. Confirm the command to resolve this.
What does 'Battery error for clock' mean on A&D HR-250AZ Scales, and how to resolve it?
A 'Battery error for clock' on your A&D Scales means the back-up battery power for the clock was lost completely. After pressing a key, adjust the date and time. Even if the back-up battery power is lost, the balance performance will be normal. If this error appears frequently, repair is required.
What to do if A&D HR-250AZ show a stability error?
If your A&D Scales display a stability error, it is likely due to an environmental problem. To resolve this, prevent vibration, drafts, temperature changes, static electricity, and magnetic fields. Refer to section '3. PRECAUTIONS' for detailed information on the operating environment and section '7. RESPONSE ADJUSTMENT' for adapting the balance to the environment. To return to the weighing mode, press the CAL key.
