Hi,
I use ADS 1293 with 5 lead ECG application. I follolwed the instructions about setting the corresponding registers in the datasheet (see page 41-42). Then I connected V1.RA,LA,LL and RL pins of the patient simulator to the corresponding pins of ADS 1293. When I tried to read registers from 0x37 to 0x3F for channel1, channel2 and channel3 ecg, I get nothing. Then I decided to read error registers and the main problem is about instrumentation amplifier:
ErrorRange1 = 0x01
ErrorRange2 = 0x35
ErrorRange3 = 0x01
As ADS indicates, instrumentation amplifier is out of range for CH1, CH2 and CH3, positive output near negative rail and negative output near positive rail etc.
What does errors mean in terms of the patient simulator connection? I didn't expect to receive such errors because I didn't use analog measurements. Why doesn't ADS 1293 get along with patient simulator?
Thanks.
