Why are lines jumping all over the screen while tracing with RIDGID Camera Accessories?
- B
  Bridget ParkAug 15, 2025
  If lines are 'jumping' all over the screen while tracing, it could be due to the SR-20 not picking up the signal or interference. To resolve this: * Ensure the transmitter is well connected and grounded. Point the SR-20 at either lead to confirm a complete circuit. * Try a higher frequency. * Connect to a different point in the line. * Switch to inductive mode. * Identify and eliminate any noise sources (e.g., bonded grounding). * Ensure SR-20 batteries are fresh and fully charged.

  If lines are 'jumping' all over the screen while locating a Sonde, consider the following: * Check the batteries in the Sonde to ensure they are working. * The Sonde may be too far away; try starting closer or perform an area search. * Verify the signal by placing the lower antenna close to the Sonde. * If using cast iron or ductile iron lines, increase the Proximity Threshold and try lower settings of Signal Focus Control to improve focus on weaker signals.

  David RothAug 26, 2025
  If the SR-20 is not picking up a signal, check that the correct mode and frequency are set. Examine the circuit for possible improvements. Relocate the transmitter, change the grounding or frequency. You can also modify the Proximity Threshold and/or Signal Focus Control settings.

  The Sonde may be tilted or there may be a cast-iron-to-plastic transition.

The RIDGID SeekTech SR-24LE and SR-20 are advanced utility locators designed for professionals to confidently determine the position of underground utilities. The SR-24LE model includes integrated GPS and Bluetooth® Low Energy (BLE) technology, while the SR-20 is functionally identical but lacks these features.

Function Description:

The SR-24LE/SR-20 receivers utilize an omnidirectional antenna system to measure electromagnetic signals. This system calculates the signal's orientation, strength, depth, and degree of distortion or interference, providing a comprehensive understanding of the utility's location. The device offers both visual display and multi-dimensional audio cues to make the locating experience intuitive. A key feature is its continuous monitoring of the electromagnetic field for interference from conflicting signals that could distort its shape. When distortion is detected, the SR-24LE/SR-20 emits audio cues and displays on-screen guidance, helping operators take appropriate action to avoid mis-marking utility positions. The SR-24LE also integrates GNSS for precise positioning and BLE for connectivity with Bluetooth-enabled devices.

The locators operate in two primary modes: Line Trace Mode and Sonde Mode.

Line Trace Mode: This mode allows for both Active and Passive Line Tracing.
- Active Line Tracing: Involves intentionally applying a signal onto the target line using a transmitter, either through metal-to-metal conduction or non-metal-to-metal induction. Active frequencies supported include 128 Hz, 1 kHz, 8 kHz, 33 kHz, and user-programmable frequencies from 10 Hz to 35 kHz.
- Passive Line Tracing: Detects signal energy coupled onto metallic conductors from nearby energy sources like power lines. This includes Passive Power (detecting 50 Hz or 60 Hz signals, with variations like 50 Hzx5, 50 Hzx9, 60 Hzx5, 60 Hzx9, 100 Hz, 120 Hz, and < 4 kHz), Radio Frequency Broadband (searching 4 kHz – 15 kHz and > 15 kHz), and OmniSeek Broadband Modes (simultaneously searching < 4 kHz, 4 kHz – 15 kHz, and > 15 kHz). Broadband frequencies target any signal within a specified range, including active signals.
Sonde Mode: Used to locate a sonde placed inside a pipe, conduit, or tunnel. Default sonde frequency is 512 Hz, with preprogrammed options including 16 Hz, 640 Hz, 850 Hz, 8 kHz, 16 kHz, 33 kHz, and user-programmable frequencies from 10 Hz to 35 kHz.
