Is the multimeter protected across all measurement gears? Will the multimeter be damaged if a wrong measurement gear is selected?

The multimeter is protected by a fuse at the current gear. It is also protected at the voltage gear, as it can detect voltages up to 1000V and is designed with an internal resistance of 10MΩ. There is no fuse protection at the resistance gear because a voltage excitation source exists at this gear. The measured resistance is detected by measuring the current flowing through it. If voltage is measured at the resistance gear, two voltage sources may clash, potentially damaging the multimeter. An overload-protection circuit is also designed into the multimeter.
