circuit diagrams
This refers to a resistor with position number 75 and a resistance of 1.2 ohm.
The decimal point used to indicate the value is replaced by a unit symbol (to
reduce the possibility of errors).
Resistors Capacitors:
R1: 0.1 Ωµ 1: 0.1 µF
1R2: 1.2 Ω 1µ2: 1.2 µF
1K2: 1.2 kΩ 1000µ: 1000µF
Note When repairing blood cell separators and replacing spare parts, observe the
protective ESD measures to be taken to prevent electrostatic discharge (e.g.
EN 100015-1).
