Verifying the multimeter range before measuring is a crucial safety measure because it ensures that the multimeter is set to an appropriate setting for the specific measurement being taken. Different multimeters have multiple ranges for voltage, current, and resistance, and using the wrong range can lead to inaccurate readings or even damage the multimeter or the circuit being tested.

By selecting the correct range, the technician can prevent potential hazards associated with overloading the meter or causing a short circuit. Additionally, it ensures that the readings provided will be reliable and accurate, which is vital for effective troubleshooting and maintenance work.
