I bought anti static mat from ebay, when i check resistance any two points on the mat its always zero (no ready on meter) I was wondering then how current will flow through, does it mean that its low quality useless mat?? thanks. |

You probably mean resistance is very high (inf) instead of zero. These thinks cant' be measured with a standard DMM. They need something similar to an insulation tester, which outputs a high voltage (500V or 1000V) and meaures curren then. These mats act a bit similar to a varistor, and they do not conduct current at low voltages. You can try using a piezo electic spark generator (such as in a regular lighter) on it. But I haven't tried that. Keep electronics away from such a thing though. |

However you'll need 2 largish and heavy electrodes, not just sticking 2 probes. |
