multimeter

Hi. I want to warn you in advance that I am not an electrician. Electricity is just my hobby and here at electro-tech-online.com I want to improve. I wonder if it is possible to identify a short circuit (circuit) based on the resistance of the cable to ground ?? The multimeter can display the...

Hi guys, I have a digital multimeter from TTI reference 1604, it was involved in a short circuit with no fuses installed, and now, it's not functioning as you can see in the picture, When it'spluged to power, it makes a noise from its buzzer, and displays random things on its display...

I have set up my raspberry pi to read from the MAX1204. To know if I'm reading the proper value, I use a multimeter at the input channel of the ADC, and compare it to what I read through my program. This works great. However, when I disconnect my multimeter, I don't read the same value. If I was...

I have a small pendulum driven DC generator project and I need to either record the output waveforms or log the raw data from the generator output (ideally both). The image below shows the kind of output I'm expecting based on the speed of the pendulum swing at steady state. While the image...

Hi everyone, I'm currently undertaking a project where we are taking energy readings using the FLUKE 1734 Energy Logger. The project is a trial but we want to have it looking as well as possible, so it'd be great if we could see live energy data on the application we've built. Does anybody...

How can I determine a current is AC or DC by use of an analog multimeter, or its workarounds in rudimentary tools / equipment ?

Hello. I'm not sure about this. There're multimeter that use 600 or 1000V fuses for current measurements protection (200, 400 mA or whatever), and others that use 250V fuses. All multimeters being able to work with DC/AC voltages up to 600V. What does this imply? Whats the difference between...

Hello Is this fuse of some sort? or just an empty space for installing pcb based fuse socket? **broken link removed** **broken link removed** This is the circuit board of my new cheap dmm, my last one broke when i mistakenly inserted the leads in mains while the red lead was in 10A socket. I...
