Reference zero
The amount by which the relative zero point is offset relative to absolute
zero.
Example: A displacement transducer (nominal (rated) displacement 20mm)
will be mounted at a height of 1m, measured from the machine foundation.
Absolute movement will be shown in the display.

Zero offset
Activate the
−>0<−
button to initiate a zero balance. If the value of the zero
drift is known, you can also enter it directly in the edit field. The zero bal
ance affects the gross display.
Tare
Activate the
−>T<−
button to initiate a taring. If the tare value is known, you
can also enter it directly in the edit field. Taring affects the net display.
Disable zero/disable taring
You can disable the zero balance and/or taring. The disabling applies to all
triggering mechanisms (F‐keys, control inputs, software).
A brief example will clarify the difference between a zero balance and taring:
