    Cheaper basic circuit testing.

Watch out

  • 'Power Probe 3 Plus' and 'PP3+' are the same tool; the base Power Probe 3 lacks the resistance mode.
  • A listing that includes the carrying case and extension cable is the PP319FTCRED kit, not the bare PP3+.

Why people pick it

  • Adds a 0-25 kΩ resistance mode to the PP3 platform, catching corroded connections and failing components that voltage tests alone miss
  • Applies power or ground at the tip to activate relays, motors, lights and solenoids without jumper wires
  • Min/Max voltage capture records voltage drops and intermittent faults a basic voltmeter can miss
  • Resettable 8 A thermal circuit breaker with manual reset, no fuses to replace

Know before you buy

  • Resistance tops out at 25 kΩ and there is no current, frequency-count or true RMS measurement (the PP4 adds those)
  • Not a multimeter replacement for high-impedance or precision work; it is a circuit tester first
  • The maker publishes no CAT safety rating
