KAIWEETS KT401TE Socket Tester

7-in-1 Intelligent Socket Tester – Without Batteries: This socket tester, completely without batteries, immediately detects 7 common wiring states: Correct, Earth missing, Neutral conductor missing, Phase missing, Phase/Earth reversed, Phase/Neutral conductor reversed, and Phase/Earth reversed with missing earth. Identify wiring issues during home inspections or maintenance in seconds with the colored LCD display. Voltage measurement & leakage current measurement: multifunctional socket tester shows the device on the clear color display in real time both the phase voltage (L-N) and the leakage voltage (N-E) in the range. The measurement range is designed for circuits from 200 V - 250 V. The monitoring of leakage voltage provides information on circuit stability and serves as a data basis for the maintenance of electrical systems in residential and commercial areas. RCD tester for testing the FI protection function: the integrated RCD test function simulates a residual current to verify the functionality of your residual current protection device and ensure that the FI tester triggers properly. With this RCD tester, electricians, home inspectors and DIY enthusiasts can quickly and effectively evaluate the reliability of RCD protection elements in the home or on the construction site. LCD Color Display & Data Hold: Equipped with a colored LCD display, which allows readability in dark distribution boxes as well as in bright indoor areas. The data hold function allows you to record measurements after use in hard-to-reach areas or tight spaces. Compact Outlet Tester for Versatile Applications: Thanks to the plug-and-play design, this outlet tester is ready to use immediately and, by not requiring batteries, it is ideal for long-term storage. The compact housing fits into any tool bag and makes it the perfect tool for testing in homes, offices, factories, and laboratories – a must-have for maintenance professionals and DIY enthusiasts.
