It is possible to be accidentally shocked if you’re using a multimeter that hasn’t been properly maintained. This occurs when a multimeter attempts to measure a current that is too high for its capacity or if its testing leads are faulty.
In order to prevent accidental electrocution, perform a visual inspection of your multimeter before using it. If the device or its leads seem cracked or frayed or if there are gaps between the wire and probes, replace them immediately. Many multimeters are equipped with overload protection to warn their users if the current they’re measuring is too strong.
