Fluke T5 Testers (T5-600 / T5-1000)

Fits electrical troubleshooting where you need a compact OpenJaw tester that measures AC/DC voltage, continuity, and AC current without breaking the circuit — choose T5-600 (to 600 V) or T5-1000 (to 1000 V / CAT IV 600 V).

Key advantages

OpenJaw AC current — Measure AC current to 100.0 A without breaking the circuit.
T5-600 / T5-1000 — Voltage to 600 V or 1000 V with matching CAT ratings.
Continuity + volts LED — Beeper on <25 Ω / off >400 Ω; auto-select AC/DC voltage.
Detachable SlimReach tips — Compact handheld with probe storage in holster.

Typical applications

Everyday voltage, continuity, and OpenJaw AC current checks.
Electricians choosing CAT III 600 V (T5-600) vs CAT III 1000 V / CAT IV 600 V (T5-1000).
Jobs that need a lighter tester than a full clamp meter / DMM kit.

Selection guide

Family — T5-600 and T5-1000 voltage/continuity/current testers.
Range — T5-600: AC/DC V to 600 V; OpenJaw AC to 100.0 A; Ω to 1000 Ω. T5-1000: AC/DC V to 1000 V (same current/Ω class).
Accuracy — AC V ±(1.5%+2); DC V ±(1%+1); AC A ±(3%+3 digits); Ω ±(1%+2) — T5-600 OEM sheet.
Supply — 2× AA; ~200 h zinc chloride / ~400 h alkaline.
Electrical — OpenJaw 12.9 mm; detachable SlimReach tips.
Approvals — CAT III 600 V (T5-600); CAT III 1000 V / CAT IV 600 V (T5-1000); CSA; TUV.

Common mistakes

Ordering T5-600 for a CAT IV 600 V / 1000 V CAT III duty — that rating is listed on T5-1000.
Expecting DC current through the OpenJaw — listed current path is AC only to 100.0 A.
Ignoring continuity thresholds (beeper on <25 Ω, off >400 Ω) when troubleshooting borderline connections.
Assuming clamp-meter accuracy class — OpenJaw AC current is ±(3% + 3 digits) on the T5-600 sheet.
