Cable/Harness Tester 8740N/8740NA/8740FA

8740N/8740NA/8740FA

Cable/Harness Tester

In the cable soldering process, open circuit, short circuit, and non-wetting (both cold soldering and empty solder) are the most common processing defects and the most common problems found in cable quality control.

The Microtest 8740 cable/harness and connector testers has 8740N, 8740NA (8740NAC), 8740FA four different models, and provide 128, 256 and 512 pins. These four models are different for AC/DC high-voltage measurement value. The 8740NAC is specially designed for the measurement of TYPE-C, and can also be used with current expansion box for providing the enhanced current carrying capacity of Type-C charging cables therefore ensuring quality of charging current passing through the cable.

The measurement items of 8740 cable/harness tester have (1) Open/Short;(2) Conductance; (3) Components; (4) AC Hipot; (5) DC insulation/ Hipot; (6) Quick conductance (7) Intermittence O/S, and (8) Quick Intermittence open circuit.

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 RS232, USB and the Printer interfaces.
