The display is good but the photos caught the screen refresh.
The Surger DS-13 performs a voltage calibration test sequence on initial power-up - of what looked to be 6 different voltages. It now shows trace lines that present clean and clear. To be honest, we are unsure how to fully evaluate this unit other than the cursory empirical observations mentioned above. And searching for any additional information or documentation on a Multi-Amp Surger Premiere DS-13 seems to be a practice in futility. Curiously, it's branded AVO Multi-Amp, but it looks more like a Baker Instruments product if one had to guess it.
