1 designed one Dynamic holter with AD8232.
when signal input LA &RA directly,I can get correct output.
if input signal is sine wave ,10Hz 5mV, gain=380, I can get output
But according to the national standard YY 0885-2013, the input impedance is tested. The following is the test circuit.
if input signal is sine wave ,10Hz 5mV, gain=380, I get wrong output.
I wonder why? Thanks!
