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 ...

@Freddy thanks for your response actually I am not getting Arduino nano v3.0 here but another nano version in here..although every pin is same with v3.0 but som ...

In: Measuring capacitance and ESR

Very useful article. A couple of corrections on Method1: The VRs equation should have the second square term outside the brackets, i.e.: ( Vg*sin(a) )^2 Th ...
