More Wheatstone Bridge Notes

  • Wheatstone bridges tested and working.  The 5th one had a loose connection on the positive signal line but is working now.
  • Made a slight error  in orientation.  The Amplifier is actually in the reverse order of the bridges.  The bridges go E+,S-, S+, E- and the  amplifier is E-, S+, S-, E+.  Tis means you have to cross the connections.
  • All terminals are wired and ready to be attached to strain gauges and amplifiers.
  • Best to position it so Amps are on the left side of the bridge, where ever we end up placing it on the unit.  This allows you to have testers in your left hand, while making calibration adjustments with your right.  Doing this in reverse is annoying to say the least.
