Page 7: Setting Of The Configuration Parameters
9. SETTING OF THE CONFIGURATION PARAMETERS All the configuration parameters of the device are stored in the non-volatile internal memory. When the device is switched on for the first time, an error may occur due to the lack of a sensor or the fact that the sensor that is connected is not one that is factory-programmed. - Page 8 In the event of indications different than the actual value of the input signal, the zero and the sensitivity of a sensor can be tuned: parameters 10: cALo (zero) and 11: cALG (sensitivity). In order to restore the default settings, use the file with the default configuration in the ARSOFT-CFG software. NOTE: The default transmission parameters for the AR956 programmer in the ARSOFT-CFG software are the following: 2400 bit/s, address MODBUS = 1...
