     to hide menus automatically that do not concern this sensor To be able to use the automatic sensor recognition, a meter that supports the automatic sensor recognition (e.g. Multi 3620 IDS) and a digital IDS sensor are required. In digital IDS sensors, sensor data are stored that clearly identify the sensor.
