6.5 System Specifications

System Measurement Error Budget for Voltage and Current Channel.

Notes:

1. These specifications are defined by taking one channel as reference and measured on the other channel.

2. Guaranteed by design.

3. System measurement error due to noise, individual block parameter drifts and non linearity. Based on evaluation, not tested.

4. System error due to offset is neglected because of chopper architecture.
