Power supply selection

If connected, an external power supply will be used preferentially over the internal batteries as long as the voltage remains 9V or greater. If it drops below 9V or complete disconnection occurs, the system automatically switches to the internal batteries.

Power consumption

When the external power is present, the power consumption is ~1.5W continuous with an Ethernet connection and ~66mW with a serial connection.

Clock

The instrument’s clock is maintained during brief disconnections. This time is usually sufficient to change batteries or replace desiccants.

USB-C power

The USB-C cable provides power sufficient for configuration or data download. However, the instrument requires an internal or external power supply to perform sampling.

Deployment estimates

Deployment times are estimated for lithium thionyl chloride batteries based on both memory and internal battery capacity.
