JI have a voltmeter http://www.mpja.com/Panel-Meter-DC-Snap-in-Multi-Function-100V-20A-2KW/productinfo/32541+ME
which is wired to the DC power boards under my model railroad layout. Some of the runs are 40 feet back to the control station. How can I maintain the signal strength on the wire so I have accurate voltage, amperage and current readings?
