A multimeter is an electronic tool used to measure voltage, amps and resistance across circuits. By attaching two leads to different parts of an electrical system, professionals can use multimeters to detect levels of voltage and resistance, or changes in electrical currents.
A multimeter or a multitester, also known as a VOM (volt-ohm-milliammeter), is an electronic measuring instrument that combines several measurement functions in one unit. A typical multimeter can measure voltage, current, and resistance. Analog multimeters use a microammeter with a moving pointer to display readings.
Windows writes temporary files to the hard disk which it uses as a cache during normal operation. These files are usually deleted automatically after the windows operation has been completed.
