Our device is currently controlled by certified laboratory. They encounter a problem with the chapter 126.96.36.199.1 of the standard 60601-2-25 Ed 2.0: defibrillation protection.
The test was conducted and ADAS1000 components stop. What is the problem ? How to solve?
Enclosed you will find our input schema.
Our differences from Figure 63 on page 34 from the ADAS1000 datasheet are:
- Gas discharge tubes CG5-90MS (Littelfuse).
- Our resistors are 220ohm instead of 500ohm, but resistors of our ECG cable are 10kohm.
- The resistors to RLD are placed upstream of ADAS and are 100Mohm.
