English PDF on testing electronic components, filed under schematics but in practice a general reference rather than a circuit diagram for a particular board. No device or model is named. Guides of this kind explain how to check resistors, capacitors, diodes, transistors, MOSFETs and coils with a multimeter, covering diode mode, continuity and resistance readings, and remind that in-circuit measurements can be misleading because of parallel paths. The 2.52 MB document opens in any PDF viewer and suits training or quick bench lookup.
