System Purpose

The Cable Continuity Tester is an Automatic tester designed specifically for testing Cable Harness for checking specifications such as Continuity, Insulation and Dielectric strength.

System Scope

The Cable continuity tester performs the following functions:

• The Automatic Tester has the testing capacity of n*500 lines with High Voltage Contacts expandable in steps of 500 points
• The configuration is distributed to make the system modular and easily maintainable.
• The system conducts the Continuity test at relevant points with test parameters from 3V DC to 28V DC at a current of 0.005 A to 2 A with a tolerance level of + 1%.
• The tester performs the Insulation test between specified lines or specified connectors or entire system with test parameters from 30V DC to 1500V DC, from Insulation resistance range of 100KΩ up to 200MΩ with a tolerance level of + 3% for a period of approximately 2 seconds.
• Also, the system performs the Dielectric strength test, parameters from 500V AC to 1000V AC peak volts with a tolerance level of + 2.5% for a period of approximately 2 seconds.
• The system measures the Resistance in the range of 1Ω and 10MΩ. 2 wire/4-Wire method is adopted for low resistance measurement.
• The tester is also capable of checking the Diodes, Indicators (Lamps), free ends and energizes relays, switches.
• It also has the ability to check the Capacitance in the range of 10pF to 5000µF.
