Define Element measurement system?

• Variable manipulation element

• Primary sensing element

• Data presentation element

• All of above

Whats mean Variable sensing element

• process the transducer signal, Sense and converts the input signal

• process the transducer signal (electrical signal) to make it suitable for application to data presentation element.

• an indication of the value of the measurement (readout device / display / recording etc ).

• process the transducer signal (electrical signal) to make it suitable for application to data presentation element.

Terminology of measurement system of SCALE

• A series of marks at regular intervals on an instrument that is used for measuring. The scale is depending on the pointer values

• A series of marks at regular intervals numeric extent of the values covered by a value scale.on an instrument that is used for measuring. The scale is depending on the range.

• data item is outside the range of a value scale, it is not graphed.

• A series of marks at regular intervals on an instrument that is used for measuring. The scale is depending on the range.

Terminology of measurement system for RANGE

• A series of marks at regular intervals on an instrument that is used for measuring. The range is depending on the range.

• The numeric extent of the values covered by a value scale. A range spans from a minimum value (often 0) to a maximum value.

• A series of marks at regular intervals on an instrument that is used for measuring of range.

• The numeric extent of the values covered by a value scale. An instrument that is used for measuring.

Type of errors

i. Systematic error iii. Relative error

ii. Gross Error iv. Human error

• i & ii

• i, ii , iii & iv

• i, ii & iv

• i, ii, iii

Definition of Gross Error

• Fault of person reading , incorrect recording of data or incorrect use of instruments.

• Fault of person using the instruments such as incorrect reading , incorrect recording of data or incorrect use of instruments.

• Fault of the instruments only

• Fault of person using the eyes.

What are Standard used in measurement

• International Standards

• Primary standards

• Secondary standards

• Working standards
