NCQC is sharing information about Instrument Calibration and its requirements in organizations. This ppt presentation helps organization and management trainee to understand purpose, importance and requirements of calibration management system.

1. Overview of
Instrument Calibration

2. What is Calibration?
Calibration is the activity of checking, by
comparison with a standard, the accuracy of
a measuring instrument of any type. It may
also include adjustment of the instrument to
bring it into alignment with the standard.

3. Why is Calibration Necessary?
It is impossible to make perfect hardware that would not need any
form of error correction. Even making the hardware good enough
to eliminate the need for error correction for most devices would
be extremely expensive.
The accuracy of network analysis is greatly influenced by factors
external to the network analyzer. Components of the measurement
setup, such as interconnecting cables and adapters, introduce
variations in magnitude and phase that can mask the actual
response of the device under test.
The best balance is to make the hardware as good as practically
possible, balancing performance and cost. Calibration is then a
very useful tool to improve measurement accuracy.

4. Purpose of Calibration
Calibration refers to the act of evaluating and adjusting the
precision and accuracy of measurement equipment. Instrument
calibration is intended to eliminate or reduce bias in an
instrument's readings over a range for all continuous values.
 Precision is the degree to which repeated measurements under
unchanged conditions show the same result
 Accuracy is the degree of closeness of measurements of a
quantity to its actual true value.

5. When do Instruments Need to be Calibration?
 Before major critical measurements
 After major critical measurements
 After an event
 When observations appear questionable
 Per requirements
 Indicated by manufacturer

6. What is Important of Calibration?
Calibration of a measuring equipment or working standard enables
the user to take note of the deviations and errors from the nominal
values so that corrections can be made to minimize the errors
during measurement.
A well-calibrated instrument provides the confidence to the user as
well as the consumer that the service or the product meets the
required specifications and ensures the acceptance in international
market.

7. Requirements of Calibration Management System
Each instrument requires:
 Unique identification
 A recorded history and current calibration status
 Use appropriate for the function of the instrument
Calibration procedures require
 Approved procedures for calibration
 Schedule for calibration
 Process range limits
Calibration standards and test equipment
 Must be more accurate than the required accuracy of the instrument
 Traceable back to national or international standards
Personnel
 Proof of appropriate training
 Perform within an established change management process

8. Futures of Calibration System at NCQC
 Identifies instruments that can be calibrated
 Determines calibration requirements for instruments
 Establishes calibration procedures
 Develops corrective action procedures
 Documents calibration results and activities
 Supports audit trails for calibration system

9. About NCQC - Calibration Laboratory in India
National Centre for Quality Calibration Laboratory
The NCQC was founded in 1998 for instrument calibration
laboratory. Since then, we have steadily grown by adding many
new facilities, capabilities including primary and secondary
instrumentation to become leading NABL calibration laboratory
in India. We provide calibration services to our customers in either
our own environmentally controlled multi-laboratory facility or on-site
at their location. We are NABL accredited Calibration Lab is
having wide scope of thermal, mechanical and electro-technical
instrument calibration. We had our branches in Gandhidham,
Ankleshwar, Bhavnagar, Rajkot and Vapi.
