Derived parameters - Datadisc expands your range of sensors.

A major new feature of Datadisc Pt is the ability to calculate as it records - effectively expanding your range of sensors and allowing "derived" results to be viewed straight away.

The possibilities are listed in the meter and may be selected for immediate metering.

The current list of derived parameters is as below:
