Taring
A weight can be accurately measured only from
a defined zero point. Press one of the two
t
keys
(10)
to zero the display. You can tare the display within
the entire weighing range.
Weighing
Place your sample on the weighing pan
(1)
to
determine the weight. Read off the weight indicated
in the display
(6)
only once the weight unit/stability
symbol (“
g
”, “
kg
” or a different unit as selected – see
Part 2, “Balance Operating Menu”) is indicated.

The small circle on the left in the weight display
shows that the balance/scale has been exactly
tared to “0” (±0.25 of a scale interval).
