I’m aware that exposed CRTs are lethally dangerous. The problem is that there’s no mention on how to do this in the manual I was able to find. So my questions are, Is there anything else to it, besides the pot adjustment? INP sockets are connected together and they are also connected to the mains earth when you get that in your house.

Z80user on December 03, Just remember that the outer metal part of both inputs and the TRIG. If I mix both channels and add the inverse of the second one I can cancel this noise. 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. The ones I’ve found are in German, and contain schematics only, no instructions.


The procedure being as follows: So I assume the “calibrated position” must be recalibrated. 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. Turn all three red variable controls fully counter-clockwise. You can find the service manual here: Repeat this test with the other probe.

This question appears to be off-topic. Until now I fix some switch, create a new stop for one switch and replace 3 capacitors but now I don’t know what I can do with this noise.

Disconnect the power cable, and remove the scope cover; Place the scope vertically, so the VR pot can be reached and the front panel still reachable ; Reconnect the power cable, turn the scope on, and supply the reliable 5 volts in my case it was through a digital Lab PSU, so I also rechecked with 1 volts, 2 volts, etc.

I think the missing knobs can be replaced by something from the ELMA range. How to calibrate the vertical sensitivity of an old analog scope Hameg HM?

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 strange. As suggested, I just tried it and calibrated it myself. Pay also attention to the red variable controls. The configuration now is two crocodrile wires with a resistor of 2K2 between both red wires, this noise come mostly from the channel 1 on channel 2 I get some noise but a bit lower.


Hameg weird 50Hz signal It’s probably just as simple as adjusting the pot marked Y-gain. Is it a terribly bad idea to do the adjustment while the scope is naked and powered?

I play with my fingers on multimeters too and saw the resistance between both hands is lower then between 2 fingers on the 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.

Nothing scary, the scarier part was the amount of spider webbing inside: Did you miss your activation email?
