[Cause]
This alarm provides additional information for the excessive increase error alarm. Old is the previously measured wear amount, and New is the wear amount measured this time (the abnormal detection target). The difference between them is the increase error amount.
[Countermeasure]
Refer to SVGN-32 or SVGN-33. Note: If the wear amount measured this time is near 0mm, wear measurement may have been executed without the electrode tip replacement flag being displayed even though the electrode tips were replaced.
