30-250V Portable Digital Socket Tester DetectorD Voltage Tester EU US UK Plug Ground Polarity Phase Check Tool Color Screen

Description: -The polarity detection of the three hole power socket wiring -The protection function detection of the leakage switch -It can quickly and accurately detect the wiring -Widely used:fire protection/laboratory/factory/family ▶Voltage measurement 1. The normal voltage range of zero fire line is plus or minus 10% of the local standard voltage. If it is too high or too low, it may be because the circuit load is too high or the power supply is too low/ too high. 2.The normal voltage of zero-earth wire is le than 2V, if too high maybe it is because there is current leakage, or the three phase-sequence is out of balance or there is signal interference in the circuit. ▶RCD TEST Please turn off all electrical appliances before using this function,and do so with permiion to ensure that the power outage will not cause any harm. ▶Six Test status analysis show 1.Wire is corect 2.Miing zeo line 3.Miing ground 4.Fire gound reserse 5.Fire zero reserse 6.Mismatch and lack ofd Specification: -Zero-live voltage measure (L-N):30-250V/(50-60HZ) -Zero-earth voltage measure (N-E):0.1-10V /(50-60HZ) -Working envment Temp 0 C-40C /humidity (20%-70%) -Storage envment Temp 10°C-50°C/humidity (20%-80%) -RCD Current:>30mA -RCD Working voltage:220V+20V -Battery:AAA * 2 battery(not included)
