Electronic Measurements

A focus on measurements in the electronic and electrical engineering.

Articles

Everyone who is involved in the electronic or electrical engineering will face sooner or later measurement challenges. Experience shows that an error is quickly made. Both the simplest as the more complex measurements could hold a real snag in it. Meettechniek.info will provide information and insight into various measurements and their background.

New wattmeter project

As a result of the popularity of the DIY Arduino Wattmeter and questions about additional functionality, the idea arose to design and produce a more practical w ...

Thermoelectric voltages of shunt resistors

Be careful when selecting a resistor for your shunt when low burden voltages are required. Beside the temperature coefficient, the thermoelectric voltages will ...

True RMS or a true lie?

The two true RMS multimeters who I'm using on a daily base measure the RMS-value in the AC voltage and current ranges. The DC-ranges measure the mean value ...

Hello!!!! Freddy it's a nice project... I would like to inform you that my project supervisor told me to design and hardware implement a 220V digital watt ...

In: Measuring capacitance and ESR

If you measure the voltage across Rs with a voltmeter you'll get Vrs. But by only using a voltmeter you'll lose the phase relation between the voltage ...

Hi Freddy Thanks again. If i simply measure Voltage (RMS) across the Rs using Precision voltmeter (say Keithly DMM) Can i get the Vrs Directly or i will be g ...

In: Measuring capacitance and ESR

Yes, you can simply add them together. You can calculate all the parameters with the measured parameters on the oscilloscope examples.
