Instrument Verification Definition:
Instrument verification is comprised of the following:
Inspection: Each unit is inspected for damage and wear and tear. Key
functions are checked. The inspection is carried out both
external and internally. Any damaged or malfunction is noted
on the service report, providing the user with an overview of
the equipment’s status.
Maintenance: Units sent in for verification undergo a standard maintenance
procedure. The instrument is cleaned of dust and marks on
both the inside and outside. Most Boonton testers have EMI
protection cover and screen can impair visibility. Fans and
filters are cleaned to enhance cooling and the device’s
lifespan.
Verification: All specified values which can deviate over time are checked.
This includes all paths a signal can take for measurement.
Instrument Calibration Definition:
Instrument calibration is comprised of Instrument Verification PLUS the following:
Alignment: If equipment has drifted out of verification limits then the
instrument will be aligned. Alignment tunes the unit into the
center of these verification limits. This results in maximum
measurement precision. Only Boonton, as manufacturer has
the competence necessary to provide such alignment.
Documentation: Together with the calibrated instrument the user receives
documents which certify and describe the status of this
instrument. The Calibration Certification declares the
conformity of the unit with published specifications. A
Calibration Report shows all test points with rated value,
verification limit and measurement uncertainty. The service
report provides the user with status of his instrument.
