Product overview
The ExLRT is a battery-operated device that is designed to measure the resistance of complex
constructed loops for the use of electrically bonding parts within structures and sub-frames. It has an
additional joint mode that can measure the bond joints within the loops.
The ExLRT uses current couplers that non-intrusively couple an AC signal into the loop. A drive coupler
is used to inject the signal with a known voltage and a second coupler is used to measure the current.
To measure individual joints within the loop, a pair of joint probes are used to measure the voltage
presented across the joint resistance. Knowing the voltage and current for each test, the ExLRT
calculates the resistance.
