I’m replacing the power line wired with a new one but will be in months untils I will have ground wires, I life in a old house with wires cover by sewing thread something like that. Should be fine to power it on and adjust it with the cover off, just be careful not to short anything with a metal screwdriver and stay away from the HV supply to the CRT.

So my questions are, Is there anything else to it, besides the pot adjustment? I play with my fingers on multimeters too and saw the resistance between both hands is lower then between 2 fingers on hmaeg same hand if I active my muscles also I do it with radio and my body act like a antenna if I disconect it is like a flat line, I think the form of the wave form will be more like a sinwave.

Spend some time and clean the front panel and knobs and start playing with it. How to calibrate the vertical sensitivity of an old analog scope Hameg HM? The configuration now is two crocodrile wires with a resistor of 2K2 between both hhameg wires, this noise come mostly from the channel 1 on channel 2 I get some noise but a bit lower.

The problem is that hakeg no mention on how to do this in the manual I was able to find. Is it a terribly bad idea to do the adjustment while the scope is naked and powered?

Z80user on December 03, Nothing scary, the scarier part was the amount of spider webbing inside: So I assume the “calibrated position” must be recalibrated. Jones play with the chair and see the spikes on the oscilloscope the noise of 50 Hz here is common but I think the form of the signal can be a bit 2033.
