Maintenance Features (Error Messages & Troubleshooting):

The manual provides a comprehensive list of error messages and corresponding troubleshooting steps for both Weighing Mode and Calibration Mode.

Errors in Weighing Mode:

Err 02 (Load cell connection failure/A/D conversion error): Check load cell connector and signal polarity.
Err 06 (Printer connection error): Check printer connector; if issue persists, contact service.
Err 08 (ZERO/TARE key operation in unstable condition): Press ZERO or TARE key in stable condition.
Err 10 (Tare weight exceeds maximum capacity): Set tare to be smaller than maximum capacity or reset calibration.
Err 13 (Zero range deviates from set range): Confirm platform is empty; if so, perform calibration.
Over (Weight on platform too heavy): Do not exceed maximum tolerance; if load cell is damaged, replace it.

Errors in Calibration Mode:

Err 21 (Resolution exceeds limit 1/50,000): Lower the resolution by modifying allowed weight (CAL 1) or division (CAL 2).
Err 22 (Span calibration weight too low): Set span calibration weight in CAL 3 to be more than 10% of maximum capacity.
Err 23 (Span calibration weight too high): Set span calibration weight within maximum capacity (CAL 1).
Err 24 (Load cell output too small at SPAN calibration): Proceed calibration with less resolution. Recommended resolutions provided for different load cell sense voltages (2mV: 1/1,000; 4mV: 1/2,000; 10mV: 1/5,000).
Err 25 (Load cell output too large at SPAN calibration): Proceed calibration with less resolution.
Err 26 (Load cell output too large at ZERO calibration): Check if platform is empty; proceed calibration after checking in A/D TEST mode.

The manual concludes with a notice that specifications are subject to change for improvement without notice.
