2511 DC Low Earth Resistance Tester 4 1/2 LED display - 2511

*RK2511 DC Low Resistance Tester is an instrument which designed for measuring low DC resistance. It can be widely used to measure the resistance of a variety of coils, the resistance of the motor winding resistance transformer, all kinds of cable wire, the resistance of switches plugs, sockets and other electrical components.

*This instrument is used microprocessor technology to overcome the effects of DC drift, and improve measurement accuracy.

*This instrument is used the method of five ports measurement to eliminate the effects of the contact resistance and the test cable lead resistance effectively.

* Measurement error:
* Measurement error= Working error + Temperature coefficient error
* Working error
* When the temperature is 20±5C,it is ±0.2%reading±0.01%range.
* Temperature coefficient error
When the temperature is 0C~15Cor25C~40C,it is (±0.002%reading ±0.002%range)/ C.
* Measuring Current:
Range 1:about 100mA
Range 2:about 10mA
Range 3:about 1mA
Range 4:about 0.1mA
Range 5:about 0.01mA
* Pre-heat time: 15 minutes
