7.2 Calibrating Transducers with ACTA
ACTA has a built-in feature that allows calibration of transducers using the deadweight method.
When performing this task, the use of certified dead-weight equipment (arm and
weight) is needed. It is recommended that this task be carried out by Atlas Copco
service personnel or an approved laboratory.
In addition, if an Atlas Copco memory transducer is used and calibrated by means of the above method, it
is possible to download the new calibration value to the memory of the transducer directly from ACTA.
1. Place the transducer you wish to calibrate in the deadweight equipment.
2. Connect the transducer to ACTA.
