Fifteen normal resistors varying from 0.01 to 100000 Ohm. Thirteen from Bleeker’s hand, three of Huyser’s (see SM 341.3.9.13).
SM341.1: Normal resistor 0,01 Abs. Ω
SM341.2: Normal resistor 0,1 Abs. Ω
SM341.3: Normal resistor 1 Ω (Huyser)
SM341.4: Normal resistor 1 Abs. Ω
SM341.5: Normal resistor 10 Abs. Ω
SM341.6: Normal resistor 10 Abs. Ω
SM341.7: Normal resistor 10 Int. Ω
SM341.8: Normal resistor 25 Abs. Ω
SM341.9: Normal resistor 100 Ω (Huyser)
SM341.10: Normal resistor 100 Abs. Ω
SM341.11: Normal resistor 100 Abs. Ω
SM341.12: Normal resistor 1000 Abs. Ω
SM341.13: Normal resistor 10000 Ω (Huyser)
SM341.14: Normal resistor 10000 Abs. Ω
SM341.15: Normal resistor 100000 Ω
The normal resistors contain manganin for maximum stability.
From the Bleeker collection of Peter Paul de Bruijn.
