Repair & Calibration 

To ensure your instrument is operating properly, Taber Industries recommends that you institute a preventative maintenance program and have your instrument calibrated by an approved company*.  The frequency of this calibration should be based on instrument usage, experience, and good laboratory practice and become incorporated into your company's quality procedures. Annual calibration is recommended.

Calibration of MTM Equipment will be to factory requirements per the tolerances stated on the applicable certificate of calibration. A binary decision rule, utilizing simple acceptance, and simple rejection criteria will be employed to determine conformance to factory requirements.  When compliance statements are present, they are reported without factoring in the effects of uncertainty.  The acceptance zone is defined as less than or equal to the high limit, and/or greater than or equal to the low limit. The rejection zones are defined as greater than the high limit and/or less than the low limit. Single measurement results in the acceptance zone are stated as in tolerance.  Single measurement results in the rejection zone are stated as out of tolerance. When the measured result is close to the upper or lower limit of the acceptance zone the risk of false acceptance or rejections approaches a maximum of 50%.  This is a risk shared between Taber and its customers.
