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. Nothing scary, the scarier part was the amount of spider webbing inside: At high speed 0. Hameg weird 50Hz signal Did you miss your activation email? Pay also attention to the red variable controls.

The oscilloscope still a bit dush outside and on switchs, I don’t clear all of the switches. As suggested, I just tried it and calibrated it myself.

Z80user on December 03, See it as a challange! So my questions are, Is there anything else to it, besides the pot adjustment? 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. Turn all three red variable controls fully counter-clockwise. Z80user on December 04, I’m replacing 20 power line wired with a new one but will be 023 months untils I will have ground wires, I life in a old house with wires cover hamev sewing thread something like that.


Spend some time and clean the front panel and knobs and start playing with it. I know Distrelec stocks some, but they are not alone. Is it a terribly bad idea to do the adjustment while the scope is naked and powered?

hamef The procedure being as follows: 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 2203 the form of the wave form will be more like a sinwave. This question appears to be off-topic.

I’m aware that exposed CRTs are lethally dangerous. Disconnect the power cable, and remove the scope cover; Place the scope vertically, so the VR pot can be reached and the front panel haemg reachable ; Reconnect hamfg 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. INP sockets are connected together and they are also connected to the mains earth when you get that in your house. The ones I’ve found are in German, and contain schematics only, no instructions. 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 configuration now is two crocodrile wires with a resistor hamwg 2K2 between both red wires, this noise come mostly from the channel 1 on channel 2 I get some noise but a bit lower.

Repeat this test with the other probe. 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.

So I assume the “calibrated position” must be recalibrated. Someone gift me this oscilloscope and I fix some capacitators on it but I see this a bit weired.

The problem is that there’s no mention on how to do this in the manual I was able to find. Does it look like a square wave 2 hamg high and 1 wide per period?
