Description

I connected the power meter to a heater powered at 1V. The current measurement is accurate, but I didn't measure 1V.

In fact, when the DC power is off, the bus voltage changes between 10 and 20

Research direction

No files or tests are named. Start by locating the INA237/INA238 voltage-reading entry point and reproduce the report with a heater powered at 1V and with DC power off; done means the bus-voltage measurement matches the observed input instead of changing between 10 and 20.
