ST03A - Troubleshooting -> V2.7.34

The measured values do not seem realistic or are cyclically dropped

Some processors change the CPU frequency automatically according to the power management settings of the Windows to save energy. Changing of CPU frequency has bad effect on the timestamp calculation in the measurement. Wrong timestamp calculation causes that some measured values are lost, and the remaining measured values will be displayed with wrong timestamp.

To avoid this problem set the Power schemes in the Power Options Properties window (Start / Settings / Control Panel / Performance and Maintainance / Power Options) to "Always On" which will force the CPU to run at it's specified frequency.
