MULTITESTER FUSE & DIODE PROTECTION -Multitester fuse and diode protection acts as a safety barrier to prevent damage to the meter’s internal circuitry caused by overloads, incorrect range settings, or accidental high-voltage input. -The fuse protects against excessive current, while the diode protects against polarity reversals, ensuring user safety and tool durability. Fuse Protection: Primarily protects the multimeter from overcurrent damage, particularly if you try to measure high current while the probes are in the wrong jack. Diode Protection: Protects the delicate internal circuitry from reverse voltage or high-voltage transients.
