Maintenance and Service

Calibration and Adjustment
The EE471 can be calibrated/adjusted with the help of the EE-PCS. For this purpose, the probe needs to be connected to a PC via a Modbus configuration adapter.

Definitions

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 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.

Temperature Calibration and Adjustment
Depending on the application and the requirements of certain industries, there might arise the need for periodical temperature calibration or adjustment.

Calibration and Adjustment at E+E Elektronik
Calibration and/or adjustment can be performed in the E+E Elektronik calibration laboratory. For information on the E+E capabilities in ISO or accredited calibration please see www.eplusecal.com.

Calibration and Adjustment by the User

Depending on the level of accuracy required, the temperature reference can be:

Liquid bath calibrator
Dry block calibrator
Climate chamber
Handheld device (e.g. Omniport 40), please see www.epluse.com/omniport40.

Perform offset and 1- or 2-point adjustment via the E+E Product Configuration Software (see below).
