Err 4
Err 4 - Span Calibration Failure
⚙️ Model Compatibility: Essae DS-852 & DS-852G.
"Err 4" occurs if the span calibration process failed because the scale could not register a stable, correct reading during the test weight phase.
Troubleshooting Steps:
1. Verify your test weight is certified and clean (any dust or oil on the test weight will cause a failure).
2. Ensure the test weight is placed precisely in the center of the platter.
3. Ensure there is no air movement in the room—high-precision scales for gold will fail calibration if the scale detects even a slight breeze during the "stabilization" phase.
