The ESR Meter is basically an AC Ohmmeter with special scales and protective circuitry. It provides a continuous reading of series resistance in electrolytic capacitors. It operates at 100 kHz to keep ...

Now that the digital multimeter and storage ‘scope have taken over electrical troubleshooting, you’ve probably buried that old analog meter in the bottom of the box, right? Maybe there’s life in the ...

This project uses a Convolutional Neural Network (CNN) model to predict the reading of an analog meter from an image input. The model has been trained to detect the position of the needle on the meter ...

Ever wondered how engineers inspect capacitors, resistors, and inductors? The solution is frequently in a device known as an LCR meter. The tool is quite valuable since it measures three significant ...

Here’s an interesting setup using a GameBoy Advance as an interface and power supply for a PIC microprocessor. He’s got the PIC connected to the serial port of the GameBoy Advance and is able to pass ...

When was the last time you saw an analog meter in a piece of equipment? Everything these days has digital displays, and while these can be very precise, analog meters have a certain charm, and some ...

A multimeter and its test leads allow electrical workers to reach into an energized panel, touch live circuit components with the end of the test leads, and capture electrical readings like voltage, ...

Power plants use indicators to monitor process parameters such as pressure, flow, temperature, voltage, current, and vibration. Unless a facility is relatively new, it likely has analog panel meters; ...
