The "24 range" refers to the combination of positions on the rotary dial—voltages (AC/DC), currents (AC/DC), resistances, and special functions like continuity and battery testing.
Ensure you are familiar with testing procedures. For high-voltage testing (above 500V), start with the highest range setting and work down to prevent damage.
