NOTE REGARDI NG SENSE TERMI NATI ON
The sense inputs are for use with six wire load cells that have remote voltage sensing in order to
compensate for resistive loss within the cable run. If a load cell is used without this feature then connect the
positive excitation to positive sense and negative excitation to negative sense.

Suitable Charging Adaptor: approx 12vdc@300mA minimum
Correct Procedure to charge unit:
1. With the adaptor AND Junior switched OFF plug the adaptor jack into the unit.
2. Switch on the Adaptor and allow approx 12 hours to fully charge (from a fully discharged state). You can
use the unit whilst in charging mode.
