Known Limitations¶
R2311 (ES)¶
Time drift¶
The First ES devices are not using a stable Real Time Clock little susceptible to drift, meaning:
- The actual Log interval duration may differ from real-world time duration (For example the device logs data every 59 seconds instead of configured 60 seconds)
- The interval duration will likely differ from device to device
- Users must correct the real interval by calculating a trusted runtime from the start timestamp to the stop or readout moment timestamp.
Users must ensure the start and stop timestamps provided to start/stop commands are sourced from a trusted time source, like the clock of a Mobile device synchronized using network time.
Power Consumption / Management¶
The devices have limited power consumption and management optimisations:
- Power Consumption during runtime is expected between 60uA - 100uA , which provides a minimal 1 Year runtime with the standard 3 AAA batteries
- There is no automatic or command requested Off mode for storage - Users must ensure the power off switch is used to turn off the device when not used
