Reducing Settle Time When Measuring Spark Plug Wire Resistance—Meter Speed or Other Factors?

We just made a test fixture to measure the resistance of automotive spark plug wires. It works, but my boss wants to reduce the time it takes for each wire. I am giving it about 1/3 to 1/2 second from connecting the wire to taking the reading. This is so it can come down from high to near the actual value. I think they call this "Settle Time".

He thinks a faster meter will help (1,000 readings per second vs 60), but I am not sure. I think it will just give us a lot more data points and I will still need the 1/2 second.

So, who is right? Also, why does it take time?

Thanks!

Hi,

In my point of view, I think resistance meters are the same. They only differ in the amount of resistance it can handle. But it would be fair to say that a much higher capacity meter is much better and faster in terms of reading the exact resistance.
