__December 31,
2012__ - __TEST
#2 __: Here
are the results of the 2nd serie of tests with a digital
oscilloscope. The two scope probes are set to X10 and are
connected to the flat bifilar coil output. The probe Ch1 is used
to measure the voltage accross the flat bifilar coil output and
the probe Ch2 is used to measure the current i.e. the voltage
accross a 0.1 Ohm __non inductive resistor__ Mundorf MR10 10W.
Then the datas are sent to a datasheet to compute true RMS values
and the efficiency. The electrical power input of the induction
cooker is measured with a Wattmeter Energy Logger 4000F directly
connected on the power grid.

Below the setup of the TEST #2:

__TEST
#2 RESULTS__ :

Of course, the voltage, the current and the power are true RMS values...

You may download the full
datas of the digital scope HERE

Here
the accurate measurements of the __non inductive__ resistor
Mundorf MR10 de 0.1 ohm 10W. The true value is 0.09 Ohm.

The electrical power for the induction cooker is measured with a Wattmeter Energy Logger 4000F directly connected on the power grid :

The Wattmeter measures 1050 Watts at the INPUT, this is fully in
line with the 1000 Watts programmed on the induction cooker.

So, the true RMS voltage and the true RMS current computed with the datas measured with the digital oscilloscope are :
