LB620C Digital Micro Ohm Meter DC Low Resistance Meter Wire/Coil/Motor/Connectors Resistance Tester Mainly used to measure the wire resistance of cables, the contact resistance of switches, connectors, relays, the resistance of coils, motors, transformer windings and metal riveting resistance, the connection resistance test between metal components, the low-value resistance test, the ground grid and the ground electrode Resistance test of connecting conductor, contact resistance test, etc. Features: The highest accuracy is 0.01%; Direct gear shifts do not need to change lines; Built-in rechargeable lithium battery with long service life; 500 sets of data can be saved, read, and deleted; Using microprocessor technology, four-wire method test, safe, precise and reliable USB data transmission (drive free installation), can exchange data with PC in both directions; Resistance: 1mΩ, 10mΩ, 100mΩ, 1Ω, 10Ω, 100Ω, 1kΩ, 10kΩ, 100kΩ Resistance measurement range is 0.001mΩ-300.0kΩ Controllable gray and white screen backlight, suitable for use in dim places Data storage 500 sets of data can be saved, read, and deleted. "MEM" storage indication, display "FULL" symbol to indecate storage is full. Data can be transferred with the computer via USB, and themeasurement data can be analyzed by the host computersoftware, and the data can also be exported and stored andprinted. Resistance measurement of coils, motors, transformer windings. Small body, easy to carry Large capacity lithium battery Using rechargeable lithium battery, the battery cycle uses 2000mAhlarge capacity lithium battery with strong power and longer battery life.
