Scope powers up and appears to work, but waveform is off scale at top using 5V@1KHz reference. Rotating vertical position knob makes trace visible briefly. Measurement display showing 94 volts. Using separate 4MHz oscillator shows similar result. 5V@1KHz reference signal looks correct on older analog oscilloscope. Self Calibrate gives Error Code 0xc00 at step 2/38
