voltage measurement

I attempted to measure the voltage output of a Gauss meter by Polytronics (GM-504) using a lock-in amplifier (SRS-830). The measurement setup was configured by connecting the output low of the Gauss meter to the ground and the output high to the signal input (AUX) at the rear panel of the...

Hi, I'm a rising freshman at Case Western University, and I would like to make an an electronic scooter to get around campus before I move in in about two months (mid august 2023). I already have a lot of the parts I would need for the project, like motors and motor controllers, among other...

I am developing IoT device using ESP32. I am using ESP32 along with ADS1115 for voltage measurement of my equipment. My electrical device operates with following parameter : ~0-5 V DC , 25 Amp with constant current mode adjustment prior to operation. I want to measure this voltage change...

Hey all, I'm using a MAX20480DATEJ/VY+ voltage monitor for my design. Out of four inputs, I prefer to set IN1 2.5V at the same time for testing purposes. When I'm running my command, I'm constantly getting a Fault condition detected message. What can I do to make this work? I have shared the...

My digital multimeter starts fluctuating while I bring it near to my started bike even if the probes are not connected to any where .I can't read any value during that time.Therefore I cannot check my bike electrical circuit.My multimeter shows correct values when I connect to home ac supply...

Hello, Has anyone ever used one of these ZMPT101B current transformers for measuring AC voltage with a microcontroller? I’m struggling to get any linearity with it at all and I can’t understand why. Here is what I’m doing: I’m using a Variac which can produce voltages from 1vac – 330vac If I...
