Microtest 8740FA8740NA8740N

Product Description:

The newly launched series of the MICROTEST 8740 professional wire testing instrument could have three different test points, such as 128/256 and 512. Unlike the traditional wire testing instruments, the 8740 professional wire testing instrument uses dual processing unit in the inner part and carries on an analogy signal sampling measurement by DSP processor to accelerate the processing speed. By updating the principle, it is able to get rid of the past measurement methods of using the RMS-to-DC element integral and to save the time. It adds the 400MHz ARM 9 processor to design the man-machine interface operation to make the display refresh speed increase 300%.

 

It provides a completed RS232 communication to transfer the test results back to the PC terminal for storage as well. The built-in memory space can store more than 200 groups of the test files. It supports the RS232, USB and the Printer interfaces. It can be applied in all kinds of wires, connectors, and the connector and wire combine products tests and be able to meet all kinds of wire multi-point testing requirement. There is a special version for USB-C test, meet all your demand!!
