Pros & Cons

Pros

  • ✓ Tests diodes and transistors, not just volts, amps, and ohms
  • ✓ 3-1/2 digit LCD reads up to 1999 counts, legible in tight engine bays
  • ✓ Built-in overload protector shields the meter from range mistakes
  • ✓ Overload and low-battery indicators flag readings you should not trust
  • ✓ Red and black test leads included, so it works out of the box

Cons

  • ✗ Manual ranging only, so you pick the range before every reading
  • ✗ No stated true-RMS, so distorted AC waveforms may read low
  • ✗ Listing does not state a CAT safety rating for mains work
  • ✗ No listed backlight, so dark crawlspaces need a separate light

Manufacturer description

The Hiltex 40508 digital multimeter is the tool you reach for when a circuit stops behaving and you need an answer in seconds. It reads AC and DC voltage, current, and resistance, and it also tests diodes and transistors, so one meter covers battery checks, blown fuses, automotive charging systems, and household wiring faults. The 3-1/2 digit LCD counts up to 1999 and stays legible under a hood or in a cramped panel, and the included red and black probe leads plug straight in so there is nothing else to buy before your first measurement. A built-in overload protector guards the meter against…
