What this tester measures
The Fluke T5-1000 measures AC and DC voltage up to 1000V and AC current with its OpenJaw design. It also performs continuity tests with an audible beeper. It is built for electricians and technicians who need a compact, rugged tool for daily voltage and current checks on live circuits.
Practical limits of the OpenJaw interface
The OpenJaw allows non-invasive AC current measurement without breaking the circuit. The tester automatically selects between AC and DC voltage up to the 1000V rating. It does not measure DC current, resistance beyond continuity, capacitance, frequency or temperature. The 1000V rating defines the maximum voltage for safe operation on rated circuits.
Installation and common issues
The unit ships ready to use with detachable SlimReach probe tips and a compact probe storage dock. Test leads accept Fluke accessory clips for hands-free work. A 10-foot drop rating protects against typical job-site falls. Common issues include battery drain if the auto-off mode is disabled, probe tip wear on heavy use, and attempting measurements beyond the 1000V or current limits.

Questions about this item
Should I choose the 1000V model or the 600V model?
The 1000V model measures both AC and DC voltage up to 1000 volts, while the 600V model stops at 600 volts; pick the 1000V version if your work involves higher-voltage panels.
What does the 1000V rating mean when I am testing a live circuit?
It means the tester can safely measure AC or DC voltage up to 1000 volts and will auto-select the correct mode without manual range switching.
How does the OpenJaw current measurement work and what does it limit?
The OpenJaw clamps around a single conductor to read AC current without breaking the circuit, letting you measure current non-invasively up to the tester's specified range.
