Please design and produce according to international standard of EN61010-1 and international
safety code of EN61010-2-032 by abiding by safety standard of duplex insulation of CAT
600V strictly.
Adopt power measurement system which consists of chips by new high-performance and
large-capacity chip microprocessor and the latest special high-precision chips used for power
measurement with high integration level and reliable performance.They can be used t o r ealize
multiplex control, complex calculation and measurement display functions of power/harmonic
measurement system by large-capacity software.
Input measurement of three-phase three-wire, three-phase four-wire and single-phase wires
Measurement of true effective value
To measure active power, inactive power and apparent power which contains harmonics for
20 times correctly
To measure total harmonic distortion rate of voltage/current signals for at most 20 times and
harmonic components of various orders correctly
To provide USB communication record interface and special WINDOWS window image
software.
Note: UT241 has no this function.
To facilitate instrument operation by automatic range conversion circuit and panel key.
