Why Cable Locator Calibration Matters

Calibration checks, routine function checks and physical maintenance answer different questions. Use all three to keep a locating system in working order. A certificate does not replace checking the receiver, transmitter, leads and power accessories before use, and it does not prove that a site is clear.

What does calibration establish?

A calibration or verification process checks equipment against the applicable reference and specification. Keep the resulting record with the instrument's identity and service history. If repairs or adjustments were needed, record those separately rather than assuming that every certificate describes the same work.

For a locating kit, the receiver is only part of the system. The transmitter, leads, clamps, connectors, batteries and chargers also need suitable checks and maintenance.

How often should equipment be checked?

Follow the exact manufacturer's instructions and your organisation's maintenance plan, taking account of use, environment, damage and contract requirements. Radiodetection's RD8200 operation manual recommends a maintenance regime reflecting the equipment's operating conditions, with checks at different intervals. Its technical specification and the current Tx specification include recommended annual maintenance/calibration schedules; those recommendations are not a universal legal interval for every locator.

A failed function check, damage or unusual behaviour needs attention when it occurs. Do not continue using faulty equipment simply because a certificate is still within its date.

Self-test and eCert are different checks

On supported RD equipment, an onboard self-test checks instrument functions. Radiodetection's eCert service applies test signals to supported locator circuitry and provides remote calibration testing. Use the procedure and conditions specified for your model. Neither process inspects every cable, connector, battery or external accessory for physical damage.

Look after the whole kit

• Inspect the casing, terminals, connection leads, sockets and power accessories for damage or contamination.
• Store equipment clean and dry, and use the specified battery packs, adapters and chargers.
• Follow the manual's isolation and cleaning instructions. Do not clean powered or connected equipment, use high-pressure hoses or attempt internal repairs.
• Keep instrument identities, check results, service records and the next planned inspection together.

Arrange service without losing the record

Our calibration, service and repair page explains the current service route. Identify the exact instruments and accessories when arranging the work, and keep the report with the relevant kit. A maintenance plan should also allow for replacement equipment while an instrument is away.

For day-to-day locating, see tips for accurate cable locating. Safe work combines planning, service identification and excavation controls; calibration supports the equipment, not an all-clear decision.
