RCD Resistance Tester - Leakage Current Switch Tester for Circuit Breaker Detection | Electrical Safety Testing for Home & Industrial Use

Feature:1. Compact Construction: The leakage switch tester integrates the latest technology into a compact, durable, simple to use and portable instrument2. Function: Can measure tripping current, tripping time, loop resistance and on line voltage and frequency measurement of leakage switch. It is an ideal tool for electrical inspection and maintenance3. Tripping Current Measurement: Tripping time measurement. Contact voltage measurement. Loop resistance measurement4. Specification: AC Phase Voltage measurement: 0V‑440V; Frequency measurement: DC, 45HZ‑65Hz; Test current multiplier: 0.5, 1, and 55. Features: Electrical test position: 10,30,100,300,500 mA; Can store 1000 groups of test results; The data stored on the host can be uploaded to a PC through the USB2.0 portHow to Use:L‑PE live wire to ground voltage measurement1. Place the function conversion knob in L‑PE file and connect the test line according to the above picture.2, the instrument automatically measures and displays the voltage and frequency of live wire to ground.3. If you need to store the measurement results, please press the "MEMO/READ" key to store the test results.Note: live wire (L) and ground wire (E) must be connected properly when measuring l‑PE voltage.L‑N live wire to neutral line voltage measuremen
