It is the branch of engineering which deals with the measurement, monitoring, display etc. of the several of energy exchanges which take place during process operations. “In short Instrumentation is the study of Instrument.”
Instrument is a device which is used to measure, monitor, display etc. of a process variable.

What is QA/QC?
Ans: QA/QC means, “Quality Assurance / Quality Control” The purpose of this (QA/QC) is to establish the sequence of requirement for the quality of material, quality of works, its inspection, and records.
2. What is the MMG Quality Control Management System?
Ans: ISO 9001 ~ 2000
3. What is the Quality Control?
Ans: Quality Control “Those activities and techniques used to achieve and maintain the quality of product, process or service”.
4. What is Quality Control Plan?
Ans: Quality Plan “Document Specification which procedures and associated resources shall be applied by whom and when to specific project, product, process or contract”.
5. What is non-conformity?
Ans: Non-conformity “Non-fulfillment of requirement”. (Complete failure of a system, or controls, which result in completely unsatisfactory goods or services being provided).
6. What is the Specification?
Ans: Governing Document Acceptance Criteria.
7. Who are the responsible for Quality?
Ans: Everybody within all organization.
8. What is the basic responsibility of a QA/QC personal?
Ans: To ensure execution of works and comply fully as per standard and approved specs.
9. What is the basic required document for a QA/QC personal?
Ans: The basic required documents for a QA/QC personal are as following.
ITP (Inspection Test Plan): To conduct the quality check (Inspection of Witness, Surveillance and Hold Point) etc.
RFI: To conduct the inspection of completed work.
QR (Quality Record): To maintain the quality records of completed works etc.
NCR: To issue warning in case of serious violation of standard.
WP (Work Procedure): Standard procedure to execute the works.
P & ID: As a reference to ensure that the work is as per standard drawing.
MTC: To ensure that material comply the PES standard specs.
Calibration Report: To ensure parameters are function checked as per IDS.
PP (Project Plan): To ensure that the instruments are installation as per P & ID and PP as per convenience.
Hook-up: To ensure that the remote connection of pneumatic is done correctly.
Wiring Diagrams: To ensure that wiring is done correctly
ILD: To ensure that the sequential wiring is done correctly.
IDS/ISS: To ensure that the instruments comply with the basic requirement.
QCO: To issue a warning in case of little violation and observation.
DR: Discrepancy Report.
10. What are QA/QC’s ITP and QCP? Give brief?
Ans: ITP: This procedure informs about the kinds of quality check (surveillance, inspection, witness or hold pints) means quality of works is being done in proper sequences.
QCP: This procedure addresses the activities and requirement in details
