Certifications & Traceability

All of Tensitron’s handheld digital tension meters use rechargeable NiMH batteries (nickel-metal hydride) and include power supplies which can take input voltages from 100-240V and include several, interchangeable adaptors allowing for use with US, European, Australian, and other plug configurations.

Tensitron meters provide consistent, repeatable cable tension readings to ensure that the towers are not damaged by the wind and maximum solar power is generated to keep the towers operating with limited human interface.

Personnel Training:

• The Instrument Makers are the personnel that calibrate the instruments. They have been trained with written documentation as well as On the Job Training (OJT) and are certified annually to complete these tasks.
  
  Standards Used as Guidelines:
  
  
• ISO-9001
• ISO-17025
  
  Equipment Used and their Periodic Inspection and Calibration:
  
  
• Weights: The calibration weights we use range in weight from zero to 4000 pounds. Their actual weight is certified by a third party every 5 years.
• Cables: The cables used in the calibration process are inspected at least annually for dimensional tolerances according to MIL-DTL-83420N, TABLE 1. The measuring equipment used to measure and certify the cables is checked against traceable standards every 12 months. All cables that are found to be out of spec are immediately removed from the premises and replaced with cables that are measured within specification.
• Tools used: All tools used that could affect the Calibration of the Instrument are periodically (annually) checked against a Standard. These tools include but are not limited to: Micrometers, Calipers, or any other measuring instrument that is required.
• There are many other tools and equipment in the Lab that do not directly affect the Calibration of our Instruments.
  
  Tasks performed in the Lab:
  
  
• Assemble new instruments.
• Perform detailed inspection, evaluation, testing and repair of Tensitron instruments that have been returned for service by the customer.
• Calibrate these new and used instruments according to the standards mentioned previously.
• Perform Custom calibration as per the customer’s specific requests.
• Maintain history logs of the instruments calibrated/sold.
