Sartorius LP1200S digital lab scale balance analytical delta range LP 1200 g

Used Sartorius model LP1200S digital laboratory scale - 1200g maximum with 1 mg increments. The unit was working ( tested with 20g weight. the result (20.000) is pictured) but then start to show "L" or Err 54 messages. that means as per manual "the weighting pan not in place". I was not able to put it in place- will sell as-is- for parts or repair- no return. no refund. Lot F5scaleshbot
