2.2 ST30 board
The ST30 board is delivered calibrated. The printed circuit board provides setting
options for setting the measuring range, calibrating the system and resetting the
measurement to zero.

1. Jumper J1 J1 enables you to select an output signal of 0-20 mA or 0-10 V. For
example, mA is selected by setting J1 to 1.
2. Zero potentiometer The zero potentiometer can be used to compensate for a
dead load. When there is no weight on the scales, this enables the output signal
to be set to exactly 0.0 mA.
3. DIP-switch This DIP-switch enables you to change the measuring range.
4. Gain potentiometer The gain potentiometer enables you to adjust the number
of mV/V. This is used to calibrate the board.
