Nervo-ScopeĀ®/Chiropractic Repairs:

As the original manufacturer of the Nervo-ScopeĀ® and AnalagraphĀ® Chiropractic instruments, we offer complete repair and calibration services for both our products and those of other manufacturers.

Our 80 years of expertise allows us to repair a range of Chiropractic scopes both efficiently and economically. Please complete aĀ Support Request FormĀ and follow the instructions below on how to send your scope in for service ā€“ including calibration. We always give an honest and fair assessment ā€“ even if that means repairs may not be the most cost effective solution. In those instances, we offer a Trade-In Program ā€“ so donā€™t worry, we have you covered. We wonā€™t try to sell you on repairs that you donā€™t need ā€“ we are here to give you superior service, maintenance advice, and honest opinions from the experts. For assistance, please call us on 1.800.342.5335 or emailĀ sales@edl-inc.com.

Please note, we must have a completedĀ Support Request FormĀ on file before we begin working on your scope. Please be as descriptive as possible when you explain the problems you are experiencing with your scope. Provide your complete contact information including phone number and email, so we can contact you with our evaluation and findings. We try to offer free evaluations whenever possible, but certain older model scopes especially with more difficult and time consuming repairs may incur an evaluation fee (the fee is used towards the cost of the repair).


If upon evaluation we find your scope repairs to be too costly, you may be offered participation in the Trade-In Program. With the Trade-In Program, we keep your older non-working scope and give you a deeply discounted new ETS-9 or ETS-9A Nervo-ScopeĀ® in itsā€™ place. Trust EDL ā€“ we have you covered.

All scopes sent in are quoted within 10-15 business days. Please keep in mind, we make every effort to quote only the absolutely necessary repairs ā€“ and this means that occasionally upon final calibration we may discover additional work is necessary in order for the scope to get back to proper working order. If additional work is required in order to pass final calibration, your quote may change.

Things to Remember:

  • All Nervo-ScopeĀ® sales are final.
  • No returns are accepted.
  • EDL manufactures the Nervo-ScopeĀ® but we are not trained Doctors of Chiropractic and we are unable to provide instructions on how to use or interpret the scope readings.
  • All repairs under ~$375.00 are automatically repaired during the inspection/evaluation, without approval. We only contact you for approval if your repair cost exceeds ~$375.00. We will contact you with our findings and to get payment after repairs are completed.
  • More expensive repairs exceeding ~$375.00 require your authorization. If your repair cost exceeds ~$500.00, you may qualify for participation in the Trade-In Program. You will be contacted with your options before we do any repair work.
  • Any property not claimed (meaning paid for and returned to customer) within 60 days of the date of the initial quote become the property of EDL and will be discarded.
  • If your Support Request Form requests a quick turnaround and we rush your repair, an expedite fee may be applied and please note your scope will be repaired regardless of cost and without prior authorization ā€“ you will be contacted for payment after the repairs are completed.
  • Payment is required prior to return shipping.

Support Request

Before sending an instrument in for service ā€“ have you checked the battery? Many repairs may be avoided by simply changing the battery (when applicable). We recommend trying to replace the battery before sending the instrument in for servicing; it may be that a new battery restores the instrument to its proper working condition.
