FEATURES / TÍNH NĂNG
Features:
- Khả năng đo điện thế đất / Capable of measuring earth voltage.
- Giữ kết quả, xem kết quả cực đại, cực tiểu / Data hold , MAX / MIN function.
- Auto power off function:
- 2mA measuring current permits earth resistance tests without tripping earth leakage current breakers in the circuit under test.
- In addition to the facility for precision measurement, test leads for simplified two wire measuring system also supplied as standard accessories.(unit can be hung from the neck for simplified measurement).
- Automatic warning when resistance of auxiliary earth. Spikes is in excess of tolerance.
- Hợp chuẩn / Designed to meet IEC1010-1 safety standard.
