The
PROBA 50
stores every hour measured temperatures, setpoint and the status of the relay. The data of the last 28 days is
stored in the memory.
During power failure of the
PROBA50
logging will stop. The unit records that there has been a power failure.
By connecting the COM1 port of a computer to the RS 232 port of the
PROBA 50
, pre-recorded data can be downloaded to
the computer. The required software is available on request from VDH Products.
The data is stored in a DOS file, which can be edited using a normal editor.
The file will display the following data:
