Page 23 High Voltage Cable Test System from CAMI
Acton, MA — CAMI Research is introducing a new option for its CableEye HVX high voltage cable tester that permits expanded testing for contact and wire resistance as low as 1 milliohm. After checking for opens, shorts, miswires, and resistance limits, the new 4-wire Kelvin measurement applies a user- selectable test current from 10ma to 1amp to deter- mine connection resistance within 1 milliohm. The resistance profile of a model cable may be stored and used as a basis of comparison during later test- ing to reveal cold solder joints, faulty crimps, re- cessed pins, pin contact contamination, improper wire gauge, and stress-extruded wire. Four-wire measurement eliminates any effect
of fixture resistance to obtain a precise value of the unit under test (UUT) resistance only. The same high-accuracy measurement may be obtained with a short fixture attached directly to the tester, or with a large wire harness fixture that may extend a con- siderable distance to reach the UUT. Users may optionally set up a
high-current stress test for wiring by driving up to 1amp of current through each conductor, and setting a dwell time from 100ms to 3 min- utes. Increasing resistance during the dwell period may show problems not detected with a shorter measure- ment interval. Individual conductors within a
UUT may be independently disabled from 4-wire or high voltage test by
New Access+ Multitest Contacting Unit Holder
Rosenheim, Germany — New from Multitest is its Access+ contact unit holder (CUH) for the MT9510, which reportedly significantly shortens the downtime of the test cell. The new product has been developed for quick
user selection to avoid potential damage to fuses or other sensitive components. Users may also inde- pendently set different test currents for each con- ductor. The CableEye HVX system produces archival-quality reports with measurement data
for each cable tested showing the test current and 4-wire resistance in addition to test voltage, leak- age current, and insulation resistance. The report clearly denotes PASS or FAIL at the top of the re- port and will identify those wires which deviate from the expected tolerance. Reports may be print- ed, or saved by serial number as .pdf files, for fu- ture reference. Built-in Javascript comes with each Cable-
Eye software package and permits highly flexible test automation, including data export to .csv or XML files for later import into Excel or statistical analysis software. An optional API with LabVIEW
interface is also available. Contact: CAMI Research Inc., 42 Nagog Park,

and easy access to the contactors, centering plate and adapter board. The number of fixtures to open has been reduced by more than 80 per- cent. The new design substantially simplifies the demounting and mounting of the CUH. In addition, Access+ reduces
the time for maintenance on the test floor and directly improves cost of test and return on investment. Ac- cording to the company, The Access+ was developed as a joint effort of the company’s contacting and handler kit experts. It has already been suc- cessfully evaluated on the test floor. For customers with an installed base of several MT9510s, the time savings for maintenance can easily add up to
several days per year. Contact: Multitest Electronic
