I have a Tektronix 475. Both vertical amplifiers are scaled by 1-2-5 and go up to 50 volts per division. And yet both stop at 5 volts per division. Is there a trick to turning these knobs higher?
If only one were stuck at a maximum of 5v/div then I'd say a switch was malfunctioning. But both do the same and so it seems to be intentional. Any ideas on how I can get to the higher scales?
