1.1 Instrument Introduction
JK9306 series single-phase digital power analyzer (digital power meter) uses a high-speed
32-bit processor and a professional DSP digital signal processor. It has fast speed, frequency
bandwidth, full-featured, compact structure, stable testing, simple operation and good
performance. The human-machine interface is a new generation of digital power analyzer. The
main parameters that can be measured are: RMS value of voltage and current, AC component of
voltage and current, DC component of voltage and current, active power, reactive power,
apparent power, electrical energy timing, power factor, frequency, peak factor of voltage and
current, peak value of voltage and current etc. electric parameters, depending on the model of
the instrument, some instruments do not have a harmonic analysis function.
This manual covers the JK9306 single-phase power analyzer. It covers most of the power
supplies on the market with the advantages of a large input bandwidth (45 ~ 400Hz). In addition
to the basic electrical parameter measurement, the four instruments also provide intuitive
comparison functions. Input waveform display, meanwhile, the HANDLER interface, RS232C /
RS485 interface and USBTMC, USBCDC interface provided by the instrument provide conditions
for the instrument to be used in automatic sorting system and computer remote operation; the
difference between different models is mainly the current measurement range and Whether it
has the function of harmonic analysis, the maximum test current is 40A, and the measurement
accuracy is stable. The specific differences can be found in the following instrument model
comparison table.
The main features of the instrument:
4.3 inch LCD liquid crystal display;
Soft power switch;
Chinese and English optional operation interface;
Input frequency range (45 ~ 400Hz);
The range can be controlled automatically / manually;
The maximum test current is 40A (depending on the model), and the minimum current
can be 1uA (depending on the model);
Controllable synchronization trigger source;
Provide 5kHz line filter switch;
Flexible energy integration control;
Parameter comparison and Handle controllable output function;
Parameter file selection function;
Harmonic analysis function (related to specific models);
Waveform display function;
