The Fluke ST240+ is a socket tester rated 230V ac +/-10% at 4 mA, designed to verify correct wiring in standard and RCD outlets. The ST240+ detects live, neutral, and earth faults by displaying one of six wiring conditions through bright LED indicators and an integrated switchable beeper. Complies with 300V CAT II rating and carries a two-year warranty.
Electricians and maintenance workers frequently test multiple outlets across domestic and commercial installations to confirm wiring compliance with AS/NZS standards. A standard outlet test can require multiple trips to a circuit breaker panel, slowing the job and pulling a sparkie away from other tasks. The problem worsens when testing in daylight, where LED indicators are hard to see, or when working alone and managing both the tester and breaker switches simultaneously.
Licensed electricians value the ST240+ for its audible beeper that signals voltage detection, turning outlet testing into a one-person task even when identifying circuits at the breaker panel. The bright, easy-to-see LEDs and built-in reference chart eliminate guesswork. Sparkies can verify correct wiring or spot reversed live and neutral in seconds. The integrated RCD test button lets tradies confirm that RCD outlets trip as expected on-site, avoiding follow-up calls. A compact design fits into any toolbox alongside other test equipment, making the ST240+ a quick-add to site jobs without inventory complexity.
The Fluke ST240+ is not suitable for high-voltage systems, industrial distribution networks, or three-phase circuits. It is designed for single-phase 240V Australian domestic and light commercial outlets only. Do not use it on DC, variable-frequency, or non-sinusoidal power sources. The tester must be plugged into a live outlet to operate and cannot test circuits that are switched off or de-energised.

(ST240)
The tester includes a built-in RCD test button that allows you to verify RCD outlet operation with a single push. No additional equipment is needed for basic RCD testing on domestic and light commercial installations.
Yes. Plug the tester into the outlet, then walk to the circuit breaker panel. When you flip the correct breaker on or off, the beeper turns off or on, confirming the circuit connection. This method eliminates multiple trips back and forth.
No. The tester is rated for single-phase 240V outlets only and is not suitable for three-phase industrial distribution networks, high-voltage systems, or non-sinusoidal power sources.
The tester displays one of six wiring conditions (correct, earth fault, neutral fault, live fault, reversed, or earth reversed) immediately when plugged in. The bright LED indicators and reference chart allow you to read the result in seconds.
The Fluke ST240+ carries a two-year manufacturer warranty from the invoice date covering manufacturing defects. Claims are handled through authorised Fluke dealers or Sparky Direct; contact support with your order number if you need to arrange a repair or replacement.
Yes. The tester integrates a switchable beeper that you can turn off to avoid disturbing others while still seeing the LED indicator lights. The beeper can also be toggled on to detect voltage when the LED display is hard to see in bright daylight.
