Many bench multimeters have two fuses: one for the mA/uA input and one for the 10A/20A input. If you try to measure 12A on a 400mA fused port, the meter explodes (or silently melts). The PDF tells you exactly which fuse to use (e.g., F12AH250V).
In this article, we will break down exactly what the Metex M 4650CR is, what the “12” likely refers to, why “Hot” matters in a bench multimeter context, and most importantly—where you can legally and safely obtain the service manual, user guide, and schematics in PDF format.
