Repeat this test with the other probe. 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 Hammeg 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.

So my questions are, Is there anything else to it, besides the pot adjustment? You can find the service manual here: Turn all three red variable controls fully counter-clockwise. 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. Pay also attention to the red variable controls.

Z80user on December 03, If I mix both channels and add the inverse of the second one I can cancel this noise.

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.

Nothing hamsg, the scarier part was the amount of spider webbing inside: So I assume the “calibrated position” must be recalibrated. Does it look like a square wave 2 divisions high and 1 wide per period? Please login or register. How to calibrate the vertical sensitivity of an old analog scope Hameg HM? This question appears to be off-topic.

See it as a challange! Hameg weird 50Hz signal I think something is wrong. INP sockets are connected together and they are also connected to the mains earth when you get that in your house.

As suggested, I just tried it and calibrated it myself. Jones play with the chair and see the spikes on the oscilloscope the noise of 50 Hz hamfg is common but I think the form of the signal can be a bit strange. The ones I’ve found are in German, and contain schematics only, no instructions. Just remember that the outer metal part of both inputs and the TRIG.

hsmeg The procedure being as follows: The problem is that there’s no mention on how to do this in the manual I was able to find. The oscilloscope still a bit dush outside and on switchs, I don’t clear all of the switches.

Someone gift me this oscilloscope and I fix some capacitators on it but I see this a bit weired. It’s probably just as simple as adjusting the pot marked Y-gain. Spend some time and clean the front panel and knobs and start playing with it.

There was an error while thanking. Is it a terribly bad idea to do the adjustment while the scope is naked and powered? The users who voted to close gave this specific reason: Is asking on how to fix a faulty circuit on topic? 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. I think the missing knobs can be replaced by something from the ELMA range. User manual here addition to previous link.
