Having fitted two Digital Read Outs with remote display units to a home workshop milling machine I would like to replace the two 1.5 volt batteries in each unit with a small variable transformer. On investigation the two power leads in each unit with a multi–meter I find one drawing 3 volts and the other 1.5 volts (the second 1.5 volt supply takes current back to the scale sensor). I have got as far as wiring the two units in series from a 6 volt supply giving the required 3 volts to each unit but am at a loss as to providing the 1.5 volt supply in each unit. Can anyone assist, preferably in not too technical terms !
