What to do if the display suddenly disappeared in operation on KERN EW?
If the display on your KERN Scales suddenly disappears during operation, examine the built-in battery, the AJDP board, and the AC adapter to identify any potential issues.
Why does the display not get settled down on KERN EW Scales?
If the display of your KERN Scales does not settle down, doesn't repeat correctly, or the zero point drifts, inspect the stopper parts, check for any interference with the weighing pan, look for any foreign substances, and examine the tuning-fork sensor. Also, consider the impact of wind or oscillation on the scales.
How to check span is out of specified range for KERN Scales?
If the span is out of the specified range on your KERN Scales, examine the tuning-fork sensor, the AJDP board, the address data, and the coefficient memories.
