– Network booting for sensors: Network booting of sensors from DTR files.
– mA output: Support for negative span for mA output.
– Temperature bias: Parameter for temperature bias.
– Temperature hold: An ability to hold temperature when concentration is held for
wash or external hold.
– Slew rate limit filter: New output filter method to limit the maximum change
from a measurement to the next.
– Support for advanced http interface
– Instrument tags: An option to add instrument tags (max. 16 characters) to trans-
