Caltech Private Limited held a meeting to discuss calibration. They explained that calibration verifies the accuracy of instruments by comparing them to standard references. It is important to calibrate regularly to avoid false test results. The benefits of calibration include ensuring accuracy, minimizing breakdowns, and meeting certification requirements. Calibration is also important for quality improvement, safety, and interrelating quality and productivity. Caltech recommends on-site calibration for pharmaceuticals. They provide quality calibration services with accredited equipment and traceable standards.

3. Introduction
 “A set of operations, performed in accordance with a definite
documented procedure, that compares measurements performed by an
instrument to those made by a more accurate instrument or standard,
for the purpose of detecting and reporting or eliminating by
adjustment, errors in the instruments tested.”:- ISO/IEC Guide 2
 “Operation that, under specified conditions, in a first step, establishes a
relation between the quantity values with measurement uncertainties
provided by measurement standards and corresponding indications
with associated measurement uncertainties and, in a second step, uses
this information to establish a relation for obtaining a measurement
result from an indication.”:- As per VIM

4. Background
 The earliest systems of weights and measures were based on human
morphology.
 Early Babylonian and Egyptian records and the Bible indicate that length
was first measured with the forearm, hand, or finger and that time was
measured by the periods of the sun, moon, and other heavenly bodies.
 18th century, England had achieved a greater degree of standardization
than the continental countries.
 Lack of a standardized system of measurements was a source of error and
fraud in commercial and social transactions

6. Why calibrate???

7. Why calibrate???
In production test, you may encounter false passes or (equally undesirable)
false failures.
In lab, inaccurate measurements can distort your findings

8. Why calibrate???
Is your volt the same as your customer's volt?

10. When Calibrate???

11. When Calibrate???
Calibration Scheme Applicable Units
Regular calibration
For units used in daily service, when knowing the uncertainty and
traceability is important
Calibration before use
For units used infrequently or which are not in active usage but
held as spare equipment
For new units
For repaired units
Calibration if needed
For units used in other service than production,
Inspection, repairing or testing of products but which can be taken
into such service if needed
Inspection before use
For units not calibrated but which should be inspected
or adjusted before use (like adjustment of null detector)
No calibration For units which do not need calibration

12. Lengthening or shortening calibration
interval
 Lengthening the Calibration Interval
 When the measurement equipment has stability surveillance long enough
 Before lengthening the calibration interval
 the user should ensure that the maximum calibration intervals were not
exceeded
 Shortening the Calibration Interval
 When measurement equipment has drifted more than its specifications allow
 procedures should be performed:
 In cases where the drift is caused by misuse or breakage, the cause and fault
should be corrected.
 In cases where the unit has drifted without a clear cause, the calibration interval
should be shortened to half of its original length.

17. Inter-relationship between
Calibration, Quality, And Productivity

18. Inter-relationship between Quality,
Productivity and Calibration
 Productivity is one measure of the effective use of resources within an organization,
industry, or nation. Or
 According to Quality guru W Edward Deming’s, quality improves, costs
decrease because of less rework, fewer mistakes, and fewer delays (Deming
1986).
 Organizations that continually produce quality products are typically the
companies that have integrated and implemented total quality management
(TQM) strategies and practice.

23. Some Facts about calibration
 The words "calibrate" and "calibration" entered the English language as recent as
the American Civil War
 Term "calibration" was likely first associated with the precise division of linear
distance and angles using a dividing engine and the measurement of
gravitational mass using a weighing scale
 The calibration process begins with the design of the measuring instrument that
needs to be calibrated
 The selection of a standard or standards is the most visible part of the calibration
process.
 Quality management systems call for an effective metrology system which includes
formal, periodic, and documented calibration of all measuring instruments.
