2-Wire Cable Tester_8740

Product catalog summary

Specifications:
The Wire Cable Tester model 8740 series offers testing capabilities with 128, 256, or 512 testing points and can store up to 500 test files. It supports multiple Device Under Test (DUT) configurations, with a standard of 4 pieces and an optional 14 pieces. The tester can identify defective steps in sequential multiple DUT tests and automatically recognize normal or reverse connector plugins. It includes tests for capacitor polarity, diode leakage current, and both AC/DC Hipot insulation and leakage current tests. The device also performs Open/Short tests and HV Insulation/Leakage Current Tests with an extendable range of 2kΩ to 100kΩ.

Features:
The tester is equipped with advanced technology for high-speed Intermittence Open/Short and Conductance Tests. It includes a USB interface for software updates, test result storage, and file management. The device features adjustable LCD contrast and sound volume, and it includes a speaker/earphone jack. An external current expand box is available for wire buck measurement.

Accessories:
Standard accessories include a power cord, user manual CD, and test probe. Optional accessories include a remote cable, calibration kit, current expand box, multiple DUT testing expand box, and a Type-C adapter board.

General Specifications:
The models 8740N, 8740NA, and 8740FA have varying AC Hipot ranges (100-700V, 100-1000V, and 100-1000V respectively) and DC Hipot ranges (50-1000V, 50-1000V, and 50-1500V respectively). They feature AC leakage current ranges of 0.01mA to 5mA and DC leakage current ranges of 0.1µA to 1000µA. Insulation resistance ranges from 1MΩ to 1GΩ, with HV output accuracy and Hipot basic accuracy both at ±5%. The rated output is 5Vdc, and low voltage resistance ranges from 0.1Ω to 2MΩ. The measuring time is 0.01 seconds, and the test mode can be auto, manual, or external trigger.

Environmental and Physical Specifications:
The device operates within a temperature range of 15 to 35°C and humidity up to 75% RH. It features a 320x240 dot-matrix display and interfaces include a printer port, RS-232, and USB. The dimensions and weight vary by model, with the 8740-128 at 435x145x406 mm and 8.44 kg, the 8740-256 at 435x145x406 mm and 9.3 kg, and the 8740-512 at 435x190x406 mm and 14 kg.

Advanced Functions:
The tester includes programmable continuous tests, pin search, and auto-diagnosis features. It supports a range of measurements including Open/Short (2kΩ - 100kΩ), Intermittence O/S (2kΩ - 100kΩ), conductance up to 52.0Ω, resistance up to 2MΩ, and capacitance from 10pF to 1µF. Additional features include diode testing (0-7V) and insulation resistance (1MΩ - 1GΩ).
