1. The device is
composed of single-phase AC standard voltage source and standard current source
as well as DC standard voltage source and standard current source which enable
output.
2. It has
calibration function, i.e. it can correct the output value of standard sources
according to indicated values of external standards.
3. It can check
manually and self-automatically in power system all kinds of single-phase AC
power frequency indicators such as voltmeters, ampere meters, wattmeters,
frequency meter and each type of DC meters which are not above class 0.2.
4. It can generate
harmonic wave with 2~31 order, and it is can be program-controlled that the
quantity and times of the harmonic wave, and the phase angle of the harmonic
wave vs. fundamental wave.
5. There are USB interface
and RS-232 interface. It can implement automatic verification by controlling of
this device using PC via upper-computer software, and it will process and
manage the results.
