Testing is incomplete without testing for intermittent errors: a cable can pass continuity testing, yet fail intermittence testing. This same cable, if installed, could cause a critical failure - perhaps resulting in loss of life. Testing for intermittent errors is carried out using a continuous rapid stream of short test pulses … each one sweeping through the full set of test points. Known sometimes as the ‘continuous’ test, the test signal itself is sometimes mistakenly believed to be continuous. The higher the pulse rate, the more accurate the result as there is a higher statistical likelihood of ‘capturing’ the random moment of error. Testers that offer an intermittence test mode but at a slow rate will pass cables that fail on systems with high rates. Testers with the highest rates (and therefore most accurate results) will have USB interfaces. Some testers allow this rate to be adjustable, and can be set as fast as 11ms/cycle.
For greatest flexibility, and more intelligible reports, check whether the system allows tolerances to be optionally defined as % or absolute terms, as well as asymmetrically (e.g. +0%/-10%). Asymmetric tolerancing will allow you to pass more product than using more constrained test parameters (e.g. +10%/-10%).
CableEye is a highly versatile, expandable and upgradable diagnostic and Pass/Fail check Cable and Harness Test System that’s PC-based. It’s used for assembly, prototyping, production, and QC of standard or custom wire cables and harnesses The entire suite of products is powered by the same easy-to-use operating software and, with the help of its signature easy-to-interpret color-coded graphics, instantly identifies not only when there is a fault, but what type of fault and where.
