When the MMT310 leaves the factory, the measurement ranges, output
scaling and quantities have already been set according to the customer
order. The unit is calibrated at the factory and ready for use. The
transmitter is delivered with either a screw terminal connector or with a
detachable 5m cable with eight wires for serial port, analog outputs and
10 … 35 VDC power supply (requirements vary dependending on the
operating environment and output type). The wiring is described in this
section. For power supply requirements, see section Power Supply
Requirements on page 29.
