balancing and other compensation, it has not only advantages of light
weight, small size, high precision, high performance, powerful function,
original interface, ease-to-use, but also work stability.
The
product can be widely used in fields of electric energy measuring,
electric energy laboratories and other relevant industry, not only in
laboratories but also at the industrial field.
Warning:
To ensure your measuring operates more smoothly and also for the sake of
your personal safety as well as the appliance, please read this manual

1.
With cases of luxury sectional bar, A-series has a luxurious
appearance. While with aluminum cases, B-series is portable, more
smaller (it is the smallest one in domestic products of this kind.
355*145*185mm) , more lighter and easier to take.
2. Wide-range measuring:
Voltage measuring range (phase voltage):1~560V
Current measuring range: 10mA~120A
3.
Measurement of various ways: It has ability to measure AC voltage ,
current , power (active power, reactive power, apparent power) and
electric energy in four-quadrant with connection modes such as
single-phase and four-wire three-phase Y/ three-wire Δ. In addition, it
can measure reactive power and electric energy with ways of true
reactive, cross-phase reactive power, artificial neutral point of
reactive.
4. Multifunctional measurement:
a. Fundamental function
of measuring for voltage, current, phase, frequency, active power,
reactive power, power factor and error.
b. Measuring degree of stability of voltage, current and power.
c.Measuring degree of asymmetry of voltage and current amplitude in three-phase circuits.
d.Measuring degree of unbalancedness of voltage and current in three-phase circuits.
e.Measuring degree of asymmetry of the phase.
f.Display
of vector diagram. There are a variety of display ways for vector
diagram to meet the different display habits (such as clockwise
rotation, counterclockwise rotation; the choice of the benchmark
location between 12:00 o’clock and 3:00 o’clock; reference benchmark can
be changeable; phase settings for display ways: 0~360°or ±180°).
g.Waveform
display, harmonic analysis, distortion calculation. Display of
frequency spectrum, it can display the amplitude, contents and phase of
the harmonic. Frequency spectrum can be enlarged.
h.Dem measurement.
i.Measurement of space magnetic induction intensity.
j.Measurements of voltage drop of the device’s dotted terminal.
k.Measurement of the constant and frequency of the meter to be adjusted.
l.Measurement of power of fundamental wave.
m. It can adjust errors of three different kinds of meters (active power, reactive power, apparent power, voltage, and current).
n.There
are three ports for pulses to output. And its constants can be set
automatically or manually. Types of constants can be set also: active
power, reactive power, apparent power, voltage, and current.
o. It can check the comprehensive error of device composed of three single-phase meters.
p. It can be used as three single-phase standard meters.
5.
Measurement of power for fundamental wave: not only could it measure
the full power (including powers of fundamental wave and orders
harmonics), but also the fundamental power only.
6. Adjustment of
electric energy error: it can adjust the estimate value of standard
deviation and computation error of electric energy meters as well as
calibration device for energy meter. Moreover, counts of pulse and
constants of meters to be checked can be set automatically so as to work
effectively. Especially for the multi-constant standard meter and the
energy meter calibration device, it will be more convenient. By adopting
the use of special compensation techniques, error-beating would not be
large because of the small load (the low frequency of the energy
pulses). It can display the current error, the value of the standard
deviation estimate and the average error.
7. Harmonic analysis: it can analyze the harmonics of voltage and current under 51 orders.
8.
Display of data and graphics: it can display the measuring working
condition and multiple measuring data directly. It can also display the
waveform of the voltage and current to be measured, the phase vector
graph of the voltage and current and waveform of harmonic analysis
directly.
9. The measuring range can be switched manually or automatically.
10. With storage function, it can store 30 groups of data records which can be searched and browsed according to the condition.
11. With the function of Pinyin input method: Chinese Character, alphabet and symbol can be inputted.
12.
Connection: the input port of the wide-range current is a public port,
and there is no need to change connection mode while the current is
changed, so it is very convenient to use.
13. Multi-use: it can be
used as a standard-meter, also as a calibration device for energy meter.
It can be used alone, with PC by remote communication, also with
calibration device.
14. Multiple ports for communication: RS485, RS232, USB, and baud rate can be set when using asynchronous communication.
15. With 6.4(or 5.7)-inch 640*480 pixel TFT display, it shows clearly and colorfully.
16. Operation: human orient design, reasonable combination of the function and simple operating.
