Resistance values of E-series according to IEC 60063 shall be used.
The qualification of resistance values below or beyond the specified resistance values is permitted, if they fulfil the require-ments of the closest stability class (e.g. RR 1608M 1 % > 260 kΩ shall fulfil the requirements of stability class 0,1 or 0,25).
