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. All measured data is saved into memory. If desired, High or Low limit monitoring (LHM and LLM bits of
control register) can also be switched on. Violation of limits will raise an alert so that it can be discovered
quickly without the need of reading the whole logged memory (Control register bit L=1, bit M=0).
Event mode.
Tag is continuously measuring the sensor value with an interval defined by Sample Time register. If
this value is violating either lower or higher limit, the value will be logged (Control register bit L=1, bit M=1).
