Question
Which of the following can damage a multimeter?
Answer Options
- A) Attempting to measure resistance using the voltage setting
- B) Failing to connect one of the probes to ground
- C) Attempting to measure voltage when using the resistance setting
- D) Not allowing it to warm up properly
Correct Answer: C
Explanation
A multimeter is an extremely useful but fragile tool. It can be easily damaged if used improperly, particularly when measuring resistance or current. The ohmmeter function (resistance setting) is designed to operate with very little current and is protected only by a fuse or a small amount of internal resistance.
Attempting to measure voltage when using the resistance setting is extremely dangerous to the meter. The high external voltage will immediately push excessive current through the meter’s delicate circuitry, likely blowing the internal fuse or destroying the meter’s measuring resistor.
