Calibration / Adjustment
Definition of terms:
Calibration
The calibration documents the accuracy of a measurement device. The device under test (specimen) is
compared with the reference and the deviations are documented in a calibration certificate. During the
calibration, the specimen is not changed or improved in any way.
Adjustment
The adjustment improves the measurement accuracy of a device. The specimen is compared with the
reference and brought in line with it. An adjustment can be followed by a calibration which documents
the accuracy of the adjusted specimen.
The adjustment of EE1900 can be performed with the EE-PCS Product Configuration Software, free
download from www.epluse.com/configurator.
