- Test for 180-250VAC circuit
- Detect faulty wiring status in 3 wire receptacle
- Checks the earth loop impedance of the wiring under test, andindicates the range that the measured earth loop impedance fallswithin
- This socket tester will give indications as well if the mainvoltage is below 210V or above 250V
- It could perform self test after plug-in
- 30mA leakage current measurement
