AD8237 Strain Gauge Testing

Hi All,

I'm trying to find alternate economic way to test performance of strain gauge circuit (attached below) over resolution below 1mV. So far, I have tested it for 1mV differential inputs at Instrumentation Amplifier's input with help of Freescale Kit DAC's output.DAC output was fed into inputs of INA ( Instrumentation Amplifier ) to check its performance at a high level.
