7. Start-up procedure
7.1 Basic start-up procedure
The sensor is an absolute measuring device and must be parametrised during the commissioning
procedure.
The following points must be checked before parametrisation:
•
The correct installation of the sensor in the conveyor line.
•
The correct connection between the sensor and the Evaluation unit.
•
A warm-up time of approx. 5 minutes before starting parametrisation and after switching on the
sensor's power supply.
At the beginning of the calibration, it must be checked whether the correct sensor is selected under
the menu item
7. System
. If the correct sensor has been selected, the desired measuring range and the
physical unit are entered in
1. Measuring range
.
Once all parameters are correctly stored, the sensor transmits a measured value. No extensive
calibration is required beyond the defined distance of both measurement antennas and the internal
correlation of the measured values. Should the measured speed nevertheless deviate from a reference
speed, the value can be adjusted via
2.1 Calibration factor
.
If the sensor shows the process indicator
P1000
, the sensor has been installed against the direction of
flow. Using function
7.2.4 flow direction
, the measuring direction can be rotated and the measurement
can be made.
7.2 Datalogger function in the software
To determine the raw values via the Datalogger function of the PC software, a file path first must be
stored. The file path and file name can be selected by clicking on the folder icon next to File name. If
the file path is stored, the sample rate could still be changed, this is recommended for long recordings.
For determining the raw values for a calibration point, the default setting of 1 (raw value) / second is
recommended.
To start the datalogger, the
On-line representation
must be started. As soon as the checkbox on
Datalogger activated
is set in the on-line display, the recording starts and the log file is created in the
background.
The data logger is only activated as long as the on-line representation is open. If the window of the on-
line display or the entire software is closed, the data recording is aborted. If the data logger is activated,
a message window also appears before the on-line representation is closed.
For an evaluation of the recorded log file, it must be opened with Excel or a similar program.
