Inspect the glass fuse (usually a fast-acting 0.5A / 250V fuse). Pop it out and replace it if the internal wire is broken.
: Today, these meters are celebrated as "Oldie but Goodie" tools. Many are still operational after 40+ years, often needing only a fresh 1.5V "AA" battery and a quick cleaning of the test leads with emery cloth to remove decades of corrosion. Core Specifications from the Manual
: The rotary switch provides 8 distinct ranges to handle various tasks, covering DC voltage up to 1000V and DC current up to 150mA. Zero-Adjustment Knobs
