Using the Platform
Great care has been taken to ensure that the hardware is ergonomically optimal in field use. Similarly, the
software design has focused not only on making valid measurements but also on making field use efficient,
convenient and intuitive.
All user choices for setups (what to measure) and preferences (how to display it) are controlled using easy to
understand lists, that can be expanded and collapsed. No more cluttered displays, choose only the
parameters you want to see.
