Many Hyper Tough models come with a strange, small, round socket labeled "hFE" (Transistor test). While transistors are obsolete for most DIYers, you can use this socket to hold small components while testing, or simply ignore it—it is largely a relic of the 1990s design.
Used for batteries and automotive electronics. Turn the dial to the V with a solid and dotted line. To test a 12V car battery, set the dial to 20V . hyper tough multimeter how to use
First, and most importantly, ensure the circuit you are testing is powered off. Measuring resistance on a live circuit can damage the meter. Turn the dial to the Omega symbol (Ω). Touch the probes to the two ends of the component. The display will show the resistance value. A reading of "OL" or "1" on the screen generally means "Open Loop" or infinite resistance, indicating a broken connection. Many Hyper Tough models come with a strange,
