Hantek cc-65

ELECTRICAL (At 23±5℃, 70% R.H. maximum)
Efficient Measure Range:
1mV/10mA: 10mA to 2 A, multimeter range is set to DC or rms AC 200mV
1mV/100mA: 100mA to 20 A, multimeter range is set to DC or rms AC 200mV
20A to 65 A, multimeter range is set to DC or rms AC 2V
Precision:
System Accuracy: The Precision of the current clamp add the Precision of the digital
multimeter or scope.
For example, if the conductor carries 100 mA current, the current clamp range will be set

Hey, even though i don't understand Spanish, i think you got a mistake in your calculations in 4:40. If your amplitude is 39mV then the Vpeak = 39/2 = 19.5V and your Vrms = Vpeak/Sqrt(2) = 19.5/1.414 = 13.8mV so the measured current with the Hantek clamp is I=Vrms * 10mA/mV =13.8mV * 10mA/mV = 137.8mA which is very close to the multimeter value which was 121mA and well within the spec of the current probe (+-1.5%+-5mV).
I'm just saying because you might drive people away from a very reasonably priced and quite accurate current probe.

Interesting. Perhaps the problem is the coupling? Because the oscilloscope Vrms is 42mV from first scope

3:49 No entiendo esa multiplicación de 41x10=480mA
