Weight indicator with 4 set points settable over the entire measuring range, logic outputs on four voltage free contacts (115Vac / 30Vdc, 0.5 A). For equal or greater weight values of setted set-point the contacts will be closed. The opening or closing of the contacts will take place taking into account the hysteresis values set in the constants. The instrument has 3 inputs with the following functions:
- Zero weight;
- Sending a string with the weighing data to a printer 24 column
- Net / gross weight or Peak function.
The calibration of the instrument can be done by setting constants parameters in the instrument setup or using a weight sample.
