Calibration Instructions
General
The instrument is supplied by the manufacturer, complete
with calibration certificate(s). A calibration period of 12
months is recommended. The actual calibration interval
depends on instrument usage and the total measurement
uncertainty acceptable for the specified application.
The UPS-III is a very precise measuring instrument and the test
equipment and conditions of test must be suitable for the type
of work. The calibration check and calibration adjustment
should be carried out in a controlled environment by a
calibration technician*.
The manufacturer offers a comprehensive and, if required,
UKAS accredited calibration service.
* A calibration technician must have the necessary technical knowledge,
documentation, special test equipment and tools to carry out the calibration
work on this equipment.
