The MESTEK ST06 is an electrical receptacle tester that examines the wiring conditions of a 3-wire 120V electrical outlet and inspects GFCI devices. The color LCD display shows the voltage, the time required to trip a GFCI device, and identifies seven common wiring problems: open ground, open neutral, reversed hot/ground, reversed hot/neutral, wired correctly, open hot, and dual open (neutral & ground).

The GFCI Receptacle Tester features a large, high-definition VA reverse display color screen for easy voltage reading and clear indication of wiring conditions. This makes it easy to identify issues, even in dim or low-light environments like electrical closets, under buildings, or behind appliances.

All GFCIs should be tested regularly to ensure they are working properly and protecting you from the risk of electric shock. To test the GFCI, simply press the TEST button, which will generate a 6mA~9mA leakage current to the ground wire. If the GFCI receptacle trips within about 3 seconds, it means the power leak-proof protection is functioning correctly.

The tester is compact and lightweight, weighing only 85g and measuring 4.4 x 2.2 x 1.4 inches, making it easy to carry when working. It features an auto-hold function to hold the reading for hard-to-reach outlets, providing convenience and ease of use. The instrument will automatically enter standby mode after 3 minutes of inactivity to save power, and a low battery indicator will remind you to change the batteries (2 x 1.5V AAA batteries included).

The GFCI Receptacle Tester has a CAT II 135V safety rating, ensuring reliable and safe electrical testing for various applications, including detecting common wiring problems in homes. MESTEK provides 24 months of after-sales service and lifetime technical support, with 24/7 customer service. If the tester is damaged within 24 months of purchase, MESTEK will replace it for free, even if the Amazon return time has been exceeded.

In summary, the MESTEK ST06 GFCI Receptacle Tester is a versatile and reliable tool for electricians, inspectors, technicians, and homeowners, capable of detecting the most common wiring faults in standard and GFCI electrical outlets. Its user-friendly features, comprehensive testing capabilities, and robust safety rating make it an invaluable asset for ensuring the safety and integrity of electrical systems.
