10 common questions and answers of the Changzhou DC low resistance tester
1., Changzhou JinAiLian produced a DC low resistance tester, a total of several products?
Answer: a total of 4 products, they are: JK2512 JK2512A JK2512B JK2511 the specific parameters of the various products please click to enter: the DC low resistance tester series products page view.
2. what is the meaning of "+2" in basic accuracy?
Answer: a word "+2" refers to the display of the last allowed to jump up and down 2 numbers.
3. is the DC resistance current constant?
Answer: test current in the corresponding range of current is constant, a total of 1A - 1uA 7 kinds of current
4. JK2512 series resistance instrument divides into several measuring ranges, what is the measuring current of each range?
Answer: 20 cents Europe, 1A, 200 cents Europe, -2 Europe is 100mA, 20 ohm is 10mA, 200 ohm is 1mA, 2K-20K is 100uA, and 200K is 10uA.
5., JK25XX series of low resistance tester, user homemade probe test clip which has to pay attention to, how should specific changes in order to ensure the accuracy of testing?
Answer: requires the probe as short as possible, and the test line should be short, four terminals should be directly attached to the probe.
6., JK2512 test copper contact resistance, the high current on it will lead to copper temperature rise, will test data floating, how to solve?
Answer: reduce the current, select a large range of testing.
7. JK2512 series short-circuit clearing, what do you pay attention to?
Answer: JK2512 series short circuit, when clearing, we must pay attention to the direction of the test chuck must be one-to-one correspondence, otherwise it can not be zero.
8. is it possible to measure four terminal resistors?
Answer: the test clip must be reformed before testing the four terminal resistor.
9. JK25XX series low resistance tester, that two can have communication interface?
Answer: JK2512B and JK2515B standard HANDLER interface, optional RS232, GPIB interface, other models have no communication interface
10. DC low resistance test is mainly used to detect what products?
Answer:
The DC low resistance tester series products stable performance, easy to use, suitable for transformer and inductor coil copper resistance relay contact resistance, contact resistance, switch, connector, wire resistance component solder contact resistance, PCB line and welding hole resistance, metal detection etc.
