Your experience in these matters is extraordinary Paris! I recently read while finishing a new Jim Williams Avalanche pulse generator that the ringing in a signal caused by a choke (coil) can be limited by simply placing two higher ohmic resistors in parallel over it. Discrepancies that easily occur at square waves at higher frequencies. Since the ideal square wave contains only components of many odd-integer harmonic frequencies (of the form 2π(2k − 1)f). Sawtooth waves and real-world signals contain all integer harmonics. Which becomes a quite complex theory even though the signals look so simpel!

Albert, the tolerance of resistors in some circuits is very critical indeed. The tricky point with it is that when connecting resistors in series, the worst case scenario for this case specifically can be a 10% drift of the total value, as the individual tolerances of these resistors add up. Of course the inverse happens when they are connected in parallel. Therefore, in such a need, the parallel connection is the preferable one, depending on the availability of proper resistors of course, as it results in total tolerance improvement.
Apart from these above, there is another factor to be taken into account. If the processor measures somehow both the DC and AC voltage components through the resistive divider, then this (originally metal film, i guess) resistor cannot be replaced by wire wound resistors. The reason is the inductance factor they introduce. No matter how small it can be, it works as a choke for the high frequency pulses used for the operation of such equipment. Therefore if a circuit is responsible to measure their magnitude cannot "see" them, then a problem is already there...
That's why I always insist and suggest everyone: never do wholesale replacements in blind (without prior measurements). It's the best way for causing chaos latter on...Always go step by step and check each time your previous step before the following one...

Hi John,

Try press on the Ctrl key and scroll the mouse, the screen will become bigger.

No, I have stored these 100K pairs as 200K and want to use it another model of Induction in future as and when required. Then I can be sure! Many thanks for your comments!

Voltages are measured after it gets on. But uController checks voltages in microseconds and shuts off if it does not match with the set limit. I could not find much difference in the value of the voltages. Anyhow, you have put in a lot new points to ponder over. Many thanks for your comments!
