After Erasing the NVRAM+ I get an error E2211. What does the error indicate?

This is normal. To erase the NVRAM, the WAVEFORM and TRIGGER are held down until the power-up self-test is completed. The diagnostic system sees that two buttons are engaged. The diagnostic system reports this "error".

To continue, press Diagnostic Exit box on the display twice. Once the diagnostic system is completed, the graticule will be displayed. At the top, the following message with be displayed, "Teksecure Erase Memory Status: Erased, Instrument ID, on-time, and number of power-ups retained".
