High is relative. I don't know if you know about tolerances, but if you don't here is the deal: The fourth band of a resistor represents the tolerance and is either gold (5%), Silver (10%), or absent (20%). Multiply the tolerance % by .01 then by the resistance of the resistor. This will give you a permissible deviation value. Subtract the permissible deviation from the part's labeled resistance to get the minimum allowable resistance value of the part, or add the deviation to the labeled to get the maximum allowable resistance....If the measured resistance is between the min and max allowable resistances you just calculated based on the label consider it to be a good part, but if it is outside those bounds (or inside and really close to the edge when trouble shooting a tough fault) declare it a bad part and replace it.
