    The key takeaways are that the document outlines the calibration procedure for angle protectors to ensure reproducible and comparable results are obtained.

    The purpose of the calibration procedure is to ensure standard practices and methods of calibration are followed to obtain reproducible and comparable results and the document can be revised to meet specific project requirements.

    The general guidelines specify that calibration should be performed in a controlled environment, the UUT and reference standards should be inspected and conditioned, and any issues with the UUT should be recorded.

    TITLE : PROTECTOR CALIBRATION PROCEDURE

    7.1 The calibration should be performed in the controlled environment only. Both the
    UUT and Reference Standard equipment should be placed in controlled
    environmental condition as mentioned above for at least 30 min warm up.
    7.2 UUT should be inspected visually before starting the calibration. Visual inspection is
    done for
     Any physical damage.
     Proper Display (in Digital Bevel Protractor)
     Proper functioning of push buttons (in Digital Bevel Protractor)
     Clarity in Magnifying Glass (For Vernier type bevel protractor)
     Rusting in the blades.
     If there is any rusting, it should be removed properly in such a fashion that
    flatness of the surface should not be affected.
    7.3 If it is not satisfactory, it is to be recorded in the Data Sheet.

    8.3 For Bevel protractors, place the angle gauge between the measuring face of the
    blade and the base of the protractor and note down the reading of the protractor in
    datasheet.
    8.4 For Digital Angle Protractor place the angle gauge on the surface plate and put the
    measuring face of the protractor on the angle gauge to get the reading.
    8.5 For Mechanical type Angle Protractor place the angle gauge between the measuring
    faces of the protractor and note the reading.
    8.6 Similarly take the reading for other sizes of the angle gauge.
    8.7 Take the reading one by one in such a fashion that it covers the whole range of the
    UUT.
    8.8 Compare the maximum error found with the instrument accuracy as per BS 1685 (for
    Bevel Protractor) and as per manufacturer’s specification (for angle protractor) and
    the accuracy statement is made accordingly in the calibration certificate.

    9.0 RECORDS
    9.1 Measurement/reading shall be recorded in the appropriate Check List/Formats given
    the Attachment.
    9.2 The test report should contain the following information as minimum.
     Client/Customer Name
     Instrument Manufacturer, Make, Model, Range, Serial No & Accuracy
     Test results
