Tester Measures Leakage at Low Voltage

A new option for the HVX line of harness and cable testers permits leakage measurements of 10-gigaohm isolation at a test voltage of 100 VDC. This capability will be of interest to manufacturers requiring extremely high isolation resistance measurements at very low voltages. The option can be ordered with new testers or added as an upgrade to previously purchased systems.

The option comprises custom software and a hardware upgrade that allows an external measurement instrument to be used in combination with the HVX’s internal relay-switching matrix and reporting software. It uses the built-in external terminals of an HVX tester to accept stimulus signals from the external source, and that source’s USB or serial channel to control it and read measurement data.

CableEye internal software presents the acquired data in the standard report format used for all CableEye wiring reports. The customer will need to purchase a third party instrument, the Keithley Model 2410 SourceMeter, to obtain the new function.

Applications for such high isolation measurements include mission-critical devices with densely packed pins that would arc at higher voltages, potentially causing damage—for example, the testing of military or aerospace cables with nano connectors.

The ASSEMBLY Show South

ASSEMBLY is thrilled to return to the Music City Center in Nashville, TN for The ASSEMBLY Show SOUTH on May 1-2, 2024. This is a booming time for manufacturing and the U.S. South is right in the heart of the action. According to ASSEMBLY’s most recent annual capital spending survey, the South is projected to account for 31 percent of total spending this year, marking the fifth straight year this region has accounted for at least 30 percent of capital spending in the U.S.

In this session, manufacturers will learn how Quality function deployment (QFD) can transform consumers’ qualitative demands into quantitative parameters that will shape the design of their product and, ultimately, their manufacturing process.
