3-2-2. OUT (CPU unit → F159)
TARE ON
ON edge (0 → 1) triggers tare subtraction, nulling the Net weight. Note, however,
the user can place some restrictions on tare subtraction (see 5-12. "Restriction on
Tare Subtraction"), in which case this function can be activated only when the
reading is "Stable".
The range of tare subtraction is selectable from: whole range, or 0 <= Tare <
Capacity.
"Tare subtraction in progress" bit (14th bit of n+5 CH ) becomes 1 while this
process is underway.
※ Tare subtraction is reset when turning off power.
