• Each board has built-in reference channels for automatic calibration and testing.
• The data base is updated by scanning, with cycle times normally selected from the range
100 ms to 600 s.
• The suppression frequency is selectable from 20, 30, 50 and 60 Hz.
• The current generators for sensors deliver 2.5 mA, in accordance with DIN 43760.
• Optional software filtering and deadband limits for updating can be selected.
