reference points against which subsequent readings are compared. One should not
expect that the reference scales for meters of different brands and types (resistance
/capacitance) will read alike on the same material. The benchmark may be different
from one meter type/brand to another because a given meters’ response depends
on the material used for calibration and on the meter’s range.
