Watch out

  • The T5-1000 measures AC current through the OpenJaw fork plus voltage and continuity on leads; the T6-1000's FieldSense shows volts and amps simultaneously at the fork.
  • A T5 with probes attached is still a fork current tester, not a general multimeter: no DC amps, no true-RMS.
  • Listings bundling a holster or leads with the T5-1000 are kits.

Why people pick it

  • Measures up to 100 A AC without breaking the circuit — slide the wire into the OpenJaw fork, no metallic contact needed
  • Auto-selects AC or DC voltage up to 1000 V, so there is no range guessing on the volts function
  • CAT III 1000 V / CAT IV 600 V rating with a 3 m drop spec, unusually tough for a pocket-size tester
  • Slim Reach detachable probe tips reach into tight spaces and the lead holder allows hands-free probing

Know before you buy

  • Current is AC only — no DC current measurement (the T6-1000's FieldSense also reads only AC)
  • Averaging AC response rather than true-RMS, so non-sine loads read low
  • Resistance tops out at 1000 Ω: a go/no-go continuity and coil checker, not a general ohmmeter
  • No backlight, data hold or logging functions are listed in Fluke's specifications
