The multitester, also known as the multimeter, seems to have been invented by Donald Macadie, a British Post Office engineer.

By using a Multitester.
To test a flashlight bulb with a multitester, first set the multitester to the resistance (ohms) setting. Then, touch the probes to the metal contacts at the base of the bulb; a reading near zero ohms indicates continuity and that the bulb is functional. If the display shows infinite resistance (OL), the filament is broken, and the bulb is burnt out. Always ensure the flashlight is turned off before testing.
Donald Macadie, post-office engineer, invented the first multimeter in the 1920's. The original multimeter could measure volts, amperes and ohms.

A multitester scale refers to the range of measurements that a multimeter can make, such as volts, amps, and ohms. It provides a set of divisions for each unit of measurement that allows users to accurately read the values being measured. Different multitesters have different scales to accommodate various ranges of measurements.
