Why does A&D GF-300 Scales show calibration weight error - too heavy?
If the A&D Scales displays 'Calibration weight error - too heavy', the calibration weight used is too heavy. Please confirm the correct calibration weight value.
Why does A&D GF-300 Scales show calibration weight error - too light?
If the A&D Scales displays 'Calibration weight error - too light', it means that the calibration weight used is too light. Confirm the correct calibration weight value.
What does sample mass error mean on A&D Scales?
If the A&D Scales display a sample mass error, it means the balance can't store the sample for counting or percent mode because it's too light. Use a larger sample.
