Here are some basic troubleshooting steps to help you fix issues you may encounter when using the Power Profiler Kit II (PPK2).
- PPK2 only measuring noise
-
Make sure you have connected the PPK2 to the Device Under Test (DUT) as described in Setting up the Power Profiler Kit II.
- Measurements fluctuate when there should be a steady current draw
- Your DUT may have a power consumption that is close to a switching point causing rapid switching between the ranges and creating measurement errors/distorted plots.
- Graph response is very slow
- Avoid using Universal Serial Bus (USB) hubs and docking stations. Data plotting may consume a lot of CPU resources after some time, so ensure that sufficient resources are available.
- PPK2 not measuring anything
- Confirm that the measurement cables are connected correctly because the PPK2 cannot measure negative currents.
- Grounding
- Ensure that the DUT ground is connected to the PPK2 even in ampere meter mode.
