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 that are followed:
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. 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.
Tensitron's instrumentation falls under RoHS Product Category 8 and 9 exclusions.
"Medical devices, and monitoring and control instruments comprise RoHS Category 8 and Category 9 products respectively. The EU recognizes that these products are manufactured in small numbers and generally have a long product life. Further, these products are often used in mission-critical applications where their failure can reasonably be expected to be extremely disruptive, if not catastrophic. Since the long term effects of lead-free solder, a primary RoHS objective, cannot be known for a period of at least five years following the directive's application to the remaining eight categories, the EU has established at least a temporary moratorium of Category 8 and 9 products". 1.

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.
