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.
2.1 4 1/2 LED display,The maximum resolution is 10µΩ.
2.2 Range of testing:10µΩ~1.999KΩ ,five parts
Range 1, 200 mΩ:10µΩ~199.99 mΩ
Range 2, 2Ω: 100µΩ~1.9999 Ω
Range 3, 20Ω:1mΩ~19.999 Ω
Range 4, 200Ω: 10mΩ~199.99 Ω
Range 5, 2kΩ: 100mΩ~1.9999 kΩ
2.3 Measurement error:
Measurement error= Working error + Temperature coefficient error
2.3.1 Working error
When the temperature is 20±5C,it is ±0.2%reading±0.01%range.
2.3.2 Temperature coefficient error
When the temperature is 0C~15Cor25C~40C,it is (±0.002%reading ±0.002%range)/ C.
2.4 Measuring Current:
Range 1:about 100mA
Range 2:about 10mA
Range 3:about 1mA
Range 4:about 0.1mA
Range 5:about 0.01mA
2.5 Pre-heat time: 15 minutes
2.6 Measurement speed: 8 times / sec
2.7 Sorting Function: This function just can be used when the range is locked.
High limit setting:Set the high limit value.
Low limit setting:Set the low limit value.
HIGH sorting and alarm:When measure value>high limit value,Indicator (HIGH) will bright.
LOW sorting and alarm:When measure value>Low limit value,Indicator (LOW) will bright.
PASS sorting and alarm :When the measure value is between the low and high limit value,Indicator (PASS) will bright.
Buzzer:It will ring when the PASS Indicator is bright. It can be control by the Ring key on the panel.
