From the Main Menu, pressing Function button F1 (CABLE TESTS) will bring the user to the CABLE TESTS
pop-up menu. Choosing K-Test from the pop-up menu actives the K-Test measurement.
The CableSHARK will measure the combinations of TIP-RING, RING-GROUND, and TIP-GROUND using
the CableSHARK voltage and resistance tests to determine if K-Test is possible on the faulty pair selected. If
the measured resistance is <10 Mohms, or the voltage is > 2 VDC or negative, there may be a fault on the
line.
