This product has high temperature coeffi cient. When mea sur ing resistance, the resistance value can change due
to Joule Heating. Therefore, the mea sur ing current shall be very small in order to prevent the resistance value from
changing. (For example, when the resistor is used at RCWV, temperature of the re sis tor rise about 15 °C and the
resistance value rise a few percents.) Resistance value may also change due to the ambient tem per a ture. Resistance
value is measured at 25 °C.
