Does anyone have a Philips PM3240 Oscilloscope and know how to calibrate it as
I can't find a sqaure wave.? I recently brought a used Philips PM3240 Oscilloscope off ebay for £16, but I don't know how to calibrate it as even though I have found instructions for it online, it does not really detail how to calibrate it. It doesn't mention a built in square wave anywhere nor can I see a button or picture for a Square wave on the oscilloscope, so I assume it doesn't have one. Does anyone else have one and know how to calibrate it?
