LR-24 Cathode Testing Guide

Smith-Root Staff April 09, 2026

Testing Steps

  1. Set your multi-meter to measure resistance and connect leads to the left and right pins of the connector on the end of the cathode cable. The meter should display close to 0 ohms between the 2 pins.
  2. Move one of the leads to the bare metal cable. Again the meter should display close to 0 ohms between the pin in the connector and the bare cable. Flex the cable along its insulated length and watch the meter reading as you do. Be careful to keep the ohmmeter securely connected while flexing the cable. If the meter reading changes significantly or jumps the cable should be replaced.
