To perform zero adjustment using Z5038 0 ADJ BOARD
When performing zero adjustment, you cannot use a metal board or similar
object to replace Z5038 0 ADJ BOARD.
The zero adjustment board is used when performing zero adjustment of L2100,
L2110 PIN TYPE LEAD.
Table 3 shows cross sectional diagrams and equivalent circuits of the two con -
nection methods: connecting PIN TYPE LEAD to zero adjustment board, and
connecting that to a metal board or similar object. Table 1 (a) indicates the con -
nection using zero adjustment board, resulting in 0 V between SENSE-H and
SENSE-L. However, Table 1 (b) is the connection using a metal board or similar
object, so that 0 V is not obtained between SENSE-H SENSE-L.
