2.5.1 USB Function
DTMR series host models have a USB communication, which can be connected via DTM soft (software
and operation manual can be downloaded from Delta website). USB connection is only used for parameter
or function setting, because USB has no signal isolation, it cannot be used for long-term monitoring.
