The Loop Resistance Tester (LRT) is a unique, patented instrument that allows the integrity of cable shielding to be tested without demating the connectors.
The LRT works by magnetically coupling a low power, low-frequency AC signal onto the cable shield and measuring the resulting induced voltage and current in the loop. The complex ratio of these values is used to determine the loop resistance, which is an indicator of the quality of the electrical bonds between the cable shield, connectors and metallic surface.
Ease of operation The measurement process begins when the operator clamps two magnetic
couplers around the wire bundle or cable of interest. One coupler generates the AC signal, which is induced in the cable shield and measures the voltage around the loop. The second coupler measures the current induced in the loop. The loop current and loop voltage are digitized by precision 16-bit analog-to-digital converters, then numerically processed to
determine the loop resistance.
The operator also can use a pair of probes to measure the resistance across a portion of the loop. These probes contain replaceable tips that ensure a reliable and repeatable electronic
connection through the commonly encountered thin oxide layer on the surface of the connectors. The voltage between the two probes is simultaneously measured by the LRT using the loop current. The processor uses the measured voltage and loop current to
determine the resistance of that segment of the loop.
