Page 13: Sampling Operating Modes
Sampling operating Modes A927ZET supports three programmable Sampling Operating modes: Sampling Off. Tag is working as normal ISO180006C tag. Previous logging results are readable from memory (Control register bit L=0). Continuous mode. Tag is continuously logging the measured value with interval defined by Sample Time register. -
Page 14: Storing Operating Modes
Storing operating Modes In Continuous and Event mode, the Tag continuously measures the sensor value. When the sensor value must be stored, A927ZET can be programmed to work in four different operating modes: Sensor Data only. Tag stores only the sensor data (Control register bit D = 1, bit TL =0). ... -
Page 15: Battery Measurement And Behaviour
Battery measurement and behaviour There are several options to verify the battery status. To verify if the battery level is low, just read the failure code in the control register: the code 7 identifies a Battery Low Status (<2 V). To verify the level of the battery, you have to enable the battery logging, and then to read the last sample value. -
