My meter is a MTP 2325 and it doesn't seem to be true rms

Re: Old "Control Lighting" 2.4K dimmer voltage inputThank you. I'll take some pics

I'm not sure about what we've done, I need to ask my teacher.

I should ask my teacher about it because last year we have checked the waveform of a standard wall outlet(120V/60Hz) with an isolation tranformer between the source and the scope.

Sorry, I mean sine wave. I usually use french terms and I thought it means same thing.

Ok thanks. I'll check. I have also acces to an oscilloscope so I can check the sinus wave. At 100%(10V), I should have a complete sinus wave at the output? How should I properly connect my dimmer with the oscilloscope?

I put the max trim to the maximum. How could I know if my volmeter is RMS?

Hi No matter what adjustement and what input voltage I put(I put voltage up to 20V), the dimmer ouput seem to have a saturation point around 90V RMS. I tested it with a 150W charge, so I can't figure out what's happening. Maybe the choke have an important role so I should include it in my test?

Ok thanks, I'll try it.

It coulb be possibly a Electro control dimmer because there is a EC logo on the electronic board.

I don't know which company it comes from. As I said, it's dimmers on a "Control Lighting" dimmer pack. On the circuit breaker, it's written: Dimmer Model: 6424J. A clue would be that the choke is not a part of the dimmer module itself, it is on the back of each dimmer connector. I'm testing them...

Thank you for answering so fast. Well, what i did not explain to you is that I'm testing them with a variable power supply. This where the fear come from. On my voltmeter i get aproximately 90v when voltage input is 10. The dimmer model is PC 47B and is part of CL-R47J-6 fixed 12X2.4K dimmer...

Hi! I got old dimmer pieces in a high school and I want to control them with my Leprecon Lp-624 board that output analog 0-10V. My issue is that I think that those dimmers have analog input of 0-15V, but I don't really figure how can I get the answer. I'm afraid of burning electronic...
