F.A.Q Calibration
  • Will I be advised of repairs beforehand?
    Yes, customer service will contact you after the unit has been evaluated.
  • What is the turnaround time?
    Our standard lead-time is 5 to 7 working days.
  • How do I get my equipment to you?
    We provide pick-up of equipment in selected areas. To inquire, please contact our customer service representative. Otherwise, you can send via Gati, FedEx or any other courier services that you use.
  • Do you pick up and deliver?
    Yes, we do pick up and deliver in an area that is possible for us to travel by land.
  • Does traceability data come with the certificate of calibration?
    If you require data, you need to request it when you submit your equipment for calibration. Only then you will receive it with your certificate of calibration.
  • Will you remind me when my equipment is due for calibration?
    Yes, we will send you a recall notice a month prior to the equipment calibration due date.
  • Is there a minimum charge for an On-Site Calibration?
    Please call our sales person on this matter.
  • What information is required for the On-Site Calibration?
    An accurate list of equipment is required in order for us to send the right procedures, personnel and standards. A purchase order is also required.
  • What if I lose the certificate of calibration?
    If you lose the certificate of calibration, call customer service and drop in a written request. They will fax or mail a Xerox copy to you.
  • Can all items be calibrated On-Site?
    No, you can send a list to us and we can determine if the equipment needs to be done at our facility or yours.
  • Are you traceable to NPL?
    Yes, all calibrations performed by INDIANA are nationally/internationally traceable.
  • What is Traceability ?
    Traceability in calibration is an unbroken chain of comparisons (all having stated uncertainities) with national and international superior standards i.e., the equipment which is used as master should be calibrated with better accuracy master until the traceability reaches to National Physical Laboratory (NPL) or international standards.
  • Why measurements must be Traceable ?
    • Traceable measurements ensure the uniformity of manufactured goods and industrial processes.
    • To support equity in trade as well as compliance to regulatory laws & standards.
    • Essential to the development of technology.
    • To provide traceable calibration of test and measurement equipment is an ISO-9000 requirement (Purpose: With an eye to provide safety and fitness for use) to ensure that the products manufactured in one country will be acceptable in another on the basis of agreed to measurement standards, methods & practices)
    • Provides users with assurance of the confidentiality, validity and accuracy of the data provided while testing.
  • What Is Uncertainty & How accurate are your measurements ?
    The result of any measurement does not indicate true value, but only an approximation or estimate of the true value of the specific quantity. Therefore, the result is complete only when accompanied by a quantative statement of uncertainity. Uncertainity is defined as how close the measurement result is likely to be to the true value with reference to the value assigned to the national prototype standard for that parameter with certain probability or confidence level.
    • This is expressed in quantitative aspect of measurement quality.
    • This means traceability is automatically established when measurement uncertainity is quoted.
    • Uncertainity of measurement determines the measurement capability of a measurement standard or a measuring equipment.
  • Calibration Interval-Validity Period.
    For how long is your calibration certificate valid? Or how frequently you need to calibrate your equipment? This is a very subjective question. The answer depends on many factors like the type of the measuring equipment, usage of the equipment, man-handling and atmospheric changes that may influence the reading. In all the cases, these are variables. The calibration cycle of the equipment depends on the accuracy, sensitivity, usage, environment and the risks involved with its use ,usage, etc. Hence the calibration cycle varies from six months to 36 months depending upon the type of the equipment. Usually, it is required to be calibrated after an interval of twelve months from the date of previous valid calibration and needs frequent recalibration. The user has to fix the periodicity after seeing the results for three to four consecutive calibrations. For example, if every year it is exactly the same or within limits, he can extend the periodicity. If every year it becomes worse and he has to adjust or write down the correction chart, he has to compress the schedule. If the equipment undergoes any kind of repair, it has to be calibrated after repair. Adequate records of the test data must be maintained over a period of time to draw support for extension of validity period.
  • Difference between calibration and validation
    A calibration is a process that compares a known (the standard) against an unknown (the customer's device). During the calibration process, the offset between these two devices is quantified and the customer's device is adjusted back into tolerance (if possible). A true calibration usually contains both "as found" and "as left" data.
    A validation is a detailed process of confirming that the instrument is installed correctly, that it is operating effectively, and that it is performing without error. Because a validation must test all three of these operational parameters, it is broken into three different tests: the installation qualification (IQ), the operational qualification (OQ), and the performance qualification (PQ). It is confirmation by examination and the provision of objective evidence that the particular requirements for a specific intended use are fulfilled.
