ETCR3640 Portable Milliohmmeter DC Low Value Resistance Tester
ETCR3640 Portable Milliohmmeter DC Low Value Resistance Tester
ETCR3640 Portable Milliohmmeter, also named DC Low Resistance Tester, DC Resistance Tester, Ohm Meter and so on), It is accurate and reliable adopt with the microprocessor technology and precision 4-wire method to testing. It is mainly used for measuring the wire resistance of cables, the contact resistance of switches, connectors and relays, the low DC resistance of windings coils, motors and transformers line resistance, the connection resistance between metal rivets parts and metal components, and the connection resistance between conductors connected at ground grids poles. It is widely used in construction quality inspection station, supervision company, construction unit, lightning protection company, electric power department, ship engine factory, etc.
ETCR3640 Portable Milliohmmeter consists of the host and test leads. The host with large LCD display, clear and obvious, it can store 200 groups of data at the same time. The resistance measure range is: 1uΩ ~ 200uΩ, the max test current is : 5A, Accurate measurement by Kelvin double bridge method, no need to verify the line resistanceequip with the rechargeable lithium batteries which the battery capacity is 2000mAh, the tester operate easy and carry.
