  • Page 19: Configuration Of Sampling Rate And Low- And High-Pass Filter

    Installation and Assembly Configuration of Sampling Rate and Low- and High-pass Filter Parameters, like sampling rate or filter frequencies, are adaptable in a wide range in order to match the re- spective application. The high-pass is configured to reduce influences of low frequencies especially to hide earth acceleration. The low-pass is configured to hide disturbances at high frequency.

    Installation and Assembly Different low-pass filter settings, see Fig. 15, cause the sampling rate to change respectively. The chosen low- pass frequencies furthermore have influence on the available high-pass filter options.

  • Page 21: Operation

    Operation Operation The measurement device is already calibrated when delivered. Calibration by the user is not necessary. After connection to the operating voltage, the sensor is immediately ready for operation and independently initiates the measurement. Additionally, the digital RS485 interface is ready to react to enquiries by the master (periodic retrieval of mea- sured data).

  • Page 26 Appendix | Digital Interface RS485 A new sampled measurement value is saved to the internal buffer of the sensor. The maximum number of values which can be saved is 19 for each measurement axis. Therefore, an enquiry by the master must reach the sensor within a certain time, that depends on the set sampling rate, in order to read the content from the internal memory and ensure uninterrupted sampling (periodic enquiry).
