Standard Operating Procedure for Engineering Instruments Calibration

SOP Number: Hotel Engineering SOP  – 19

Department: Engineering and Maintenance

Date Issued: 09–Mar-2018

Time to Train: 30 Minutes

Instruments Calibration Standard Procedure:

  • All instruments used in the hotel should be calibrated for its 100% performance.

  • An authorised person/agency should be called for calibration of the instruments.

  • To check the performance, readings/measurement should be taken at least for seven days after calibration.

  • Calibration should be done every year for all the measuring instruments.

  • A master list of all instrument should be maintained to indicate which one is due for calibration.

  • The frequency of calibration of each instrument should be mentioned on the list.

  • Calibration schedule is prepared to indicate the month in which the instrument is due for calibration.

  • Each instrument due for calibration is uniquely identified.

  • Instruments should be calibrated by their manufacturer or by authorised service agencies.

  • On receipt of calibration certificate following need to be checked:

  1. Calibration masters traceability to the national standard.

  2. Acceptance of error w.r.t defined acceptance norms.

  • If the calibration report is found okay a suitable indicator in the form of sticker indicating next due date of calibration should be put on the instrument.

  • In some cases, after calibration, the instrument is found out of calibration.

  • In such case, the calibration error is received by HOD Engineering along with applicable department.

  • Necessary action including change of calibration frequency is initiated.

  • There is a possibility of any intentional or unintentional disturbance of instrument setting.

  • All users handling the instruments should be given training and instructions on safe handling and storage of instrument.
