Available measurements depend on the instrument configuration. Values
may be unavailable also in case of device failure. Read status registers or
exception status outputs to check for failures.
NOTE Only real-time data can be read from the instrument. Data that is
recorded in the transmitter’s memory (internal memory or data logger
module) cannot be read through Modbus.
