Fluke T5-1000 Electrical Tester 1000 Volts 100 Amps

SKU CH-AAYB-81TF6

Measures AC/DC voltage to 1000 V and current to 100 A with OpenJaw non-contact current sensing and continuity beeper

  • Auto-selects AC/DC voltage up to 1000 V for faster setup
  • OpenJaw measures 100 A AC current without breaking the circuit
  • Continuity beeper gives instant pass/fail feedback
  • Rugged housing survives 3 m drops for jobsite durability
  • SlimReach probes and accessory clips fit national electrical standards

Fluke T5-1000 Electrical Tester

The Fluke T5-1000 is a compact voltage, continuity and current tester rated for 1000 volts AC or DC and 100 amps. It is built for electricians and technicians who need fast, reliable measurements on live circuits. The OpenJaw design allows non-invasive current checks without breaking the circuit. A rugged housing withstands a 10-foot drop for demanding job-site use.

Upgrading from solenoid or basic testers

This tester replaces older solenoid-type units that cannot stay connected as long and lack automatic AC/DC selection. The jump is worth it when you need hands-free current measurement up to 100 amps and a continuity beeper for quick wiring verification. It also covers both 600V and 1000V models for wider application range. Buyers who require data logging or true-RMS readings will not find those functions here.

Installation and common issues

No complex installation is required; simply attach the detachable SlimReach probe tips and select the function via the rotary switch. Auto-select handles AC or DC voltage detection automatically. The main pitfalls are exceeding the 1000V or 100A limits, which can damage the instrument, and forgetting the auto-off feature that conserves battery life during extended sessions. Probe tips must match national electrical standards for safe contact.

Questions about this item

Does the T5-1000 need a separate clamp accessory to measure current?

No, the OpenJaw design measures up to 100 amps AC by sliding the forked jaw around a single conductor without extra clamps or breaking the circuit.

What is the first step when testing voltage on an unknown circuit with this tester?

Connect the black lead to COM, the red lead to V, then touch the probes to the circuit; the tester auto-selects AC or DC up to 1000 volts.

Which parts wear out and need replacement on the T5-1000?

The detachable SlimReach probe tips and the test leads can be replaced; the unit uses standard batteries that are user-replaceable.
