Klein Tools ET270 Multi-Tester

The Klein Tools ET270 is an auto-ranging digital multi-tester designed for electricians and technicians who need to measure AC/DC voltage up to 600V and resistance up to 40MOhms. It also performs audible continuity checks, battery tests and receptacle wiring inspections on North American 120V outlets. Built to survive a 6.6-foot drop, it suits demanding job-site environments.

Included Accessories and Modes

The package supplies a carrying case, test leads with CAT III/CAT IV safety caps, a receptacle test cord, instructions and two AAA batteries. The meter adds a backlit LCD, data hold, max/min recording and a manual-range override. A find mode identifies the breaker linked to a receptacle, while the GFCI trip-time display shows how long a device takes to trip. Optional magnetic hangers (Cat. Nos. 69445 or 69417) and a kickstand enable hands-free use.

Compatibility and Setup Checks

Receptacle testing is limited to North American 120V AC three-wire outlets, so confirm the local wiring standard before ordering. The unit requires two AAA cells, which are included, but spares will be needed for extended field work. If optional magnetic hangers are desired, they must be purchased separately under the listed catalogue numbers.

Questions about this item

Will the test leads or the receptacle cord need replacing after heavy use?

The kit ships with right-angle test leads and a receptacle test cord; both are consumable items that should be inspected regularly and replaced if insulation shows wear or the probes become damaged.

What measurement range hits its ceiling first during continuous testing?

Resistance measurement tops out at 40 MΩ, so very high-impedance circuits will read over-range before the 600 V AC/DC voltage limit is reached.

How hot or loud does the meter get when it is left on all day?

The unit has no fan and draws only the 2 × AAA batteries for the backlit LCD, so it stays silent and remains at ambient temperature during extended use.
