5.4 Adjustment
5.4.1 Factory setup
See below for the automatic tare and store unit’s factory setup:
Tare unit: Tare value will not be stored upon power failure
Low-pass filter active (0.4 Hz ... 12.5 Hz)
Amplification v=1
Store unit: Peak-value store (maximum value) on
Low-pass filter off
Amplification v=1
Envelope curve off
5.4.2 Tare unit adjustment
Taring is started when the voltage level on terminal 10 changes over from 0 V
to 24 V (positive edge). The tare value is held during voltage supply, even if
the voltage level goes down to 0 V again (also refer to next chapter).
NOTE
Taring with input voltages greater than "10.5 V is not possible due to
amplifier overflow. A valid tare value (<10.5 V) is signalled by an LED on
the board and the ”High” voltage level on terminal 6.
• Save tare value and protect it from power failure
The tare value can be stored for reuse after a power failure or after power-off.
For this, set switch S100/6 to ”ON” position before taring.

OFF Tare value will be lost upon power-off

ON Tare value will be permanently stored in EEPROM
