Hello, I have circuit with this amplifier, and with this circuit I amplify my pressure transducer signal from 30mV to 700mV. Amplifier works correctly, when applied pressure is increasing, multimeter shows higher voltage (range 700mV-1.3V). Both, transducer and amplifier are powered from Arduino 5V. Problem is that, when I connect scope cables to circuit output, voltage is decreasing to 500mV from 700mV (700 mV in multimeter) and when i applied more pressure to transducer, signal in scope still is about 500mV and there is no changes in signal amplitude, while there should be some increases in signal amplitude. (i attach photo with scope screen and my schematics).
