Harness Tester 8740N/8740NA/8740FA

Featured Product from Microtest Corporation

The Microtest 8740 harness tester 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.
