Determine absence of voltage using a multimeter or 2-pin voltage tester?
I once read here at gf that a multimeter is not permitted for determining the absence of voltage in low-voltage networks. A 2-pole voltage tester, such as Duspol, should be used instead. Is there any truth to this or is it nonsense???
Electrosmog measuring device?
Hello, can anyone recommend a good electrosmog meter for home use? Thanks!
Mechanical performance?
Hello, I have a speed with n = 106 1/min, M = 0.173 Nm. I want to calculate the mechanical power of an engine. The solution is P = M * w = 2*pi * 0.173Nm * 106/60 1/min*min/s = 3.84 Nm/s. But when I calculate it, I get 1.92 W? Where's my mistake?
Has the multimeter been damaged?
Hello My colleague has a Kaiweets HT118A multimeter. Unfortunately, he measured the mains voltage using the frequency setting, which is only suitable for frequency measurements up to 10V. However, according to the manual, the overload protection is set at 250V. Did this damage the multimeter?

Determine the voltage measuring range?
No matter what I calculate I just can't get the right result, can someone help me here?
How does the error of a measured value change when squared?
In an experiment, I measured the period T of a spring pendulum and calculated the corresponding absolute error. Now I need to calculate my period T^2 squared, but how does the absolute error change when I square it? Since squaring the period is simply multiplying the period by itself, I thought I could simply add…
