7 Setup and Adjustment
The EE371 probe is ready to use and does not require any configuration by the user. The EE371
factory setup corresponds to the type number ordered. Please refer to the data sheet at www.epluse.
With the help of the free EE-PCS Product Configuration Software and the optional RS232 interface
cable (order code HA010304) or with the EE-PCA Product Configuration Adapter and the according
connection cable (order code HA011063), the user can carry out sensor adjustment and calibration and
change the scaling of the analogue outputs.
7.1 EE-PCS Product Configuration Software
To use the software for changing the digital communication settings and to perform adjustments, please
proceed as follows:
1. Download the EE-PCS Product Configuration Software from
install it on the PC.
2. Connect the EE371 to the PC using the Modbus configuration cable.
3. Start the EE-PCS software.
4. Follow the instructions on the EE-PCS opening page for scanning the ports and identifying the
connected device.
5. Click on the desired setup or adjustment mode from the main EE-PCS menu on the left and follow
the online instructions of the EE-PCS
7.2 Calibration and Adjustment
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.
