1.Introduction（LYBSY-3000 AC Sampling Transmitter Calibration Device）
LYBSY-3000 is the use of
modern testing, DDS waveform synthesis, high-speed digital processor (DSP),
complex programmable logic array (CPLD), large-scale integrated power
amplifier, and the design of embedded computer system technology. It is
suitable for electric energy meter (optional), AC and DC indicating instrument
test and calibration, is ideal equipment for power system the power of product
verification and calibration.
2. Main functions and features（LYBSY-3000 AC Sampling Transmitter Calibration Device）
Domestic system, measurement and signal
integration in a module, the product of high integration, low failure rate,
small volume, light weight, fast response speed, high efficiency, high
reliability, strong function, high output power, output standard source.
Is the original operating system, starting
immediately display the test picture, without guidance program, fast response
speed, high working efficiency.
The windows and buttons (with two
functions), diversity operation, suitable for different people and habits,
simple operation.
The contents of AC / DC standard source,
direct test of various DC indicating instruments.
The automatic verification energymeter
(optional) and indicator indicators.
The voltage, current, power, phase,
frequency, harmonic with superior closed-loop output, setting a place, easy to
use software to adjust.
Thevoltage, current, phase with rich common
practical, simple operation, a little place, convenient use and high
efficiency.
Equipped with digital rotary encoder
adjustment ,easy to use,simple.
The outputvoltage, current and power are
high precision, high stability standard source,
softwarecalibration.
Output standard harmonic 2~31 times, can be
single or arbitrary superposition of many harmonic output.
Between the three-phase voltage,
three-phase current, between each phase voltage and current can be arbitrary
phase shift, so it can simulate all kinds of fault output power.
Equipped with the three-phase frequency
independent phase, frequency conversion.
Equipped with multiple alarm and protection
functions, it can detect the fault automatically and show the fault type and
location. It is safe and reliable.
The preparation of interface and software,
open interface protocol, user programmable control instruments.
Can support domestic similar product
operation software.

7.7Parameter calibration interface
This interface is
for calibration of instrument parameters. In order to ensure the accuracy of
the instrument, this interface is not open to the user.
8、Attention
The instrument must have a good grounding
in use
Check the temperature of 23 + 1 degrees.
To ensure the accuracy of the instrument,
please preheat 30 minutes before use.
Attention should be paid to the proper limits
of the objects to be measured.
instrument terminal output as standard
source, the terminal can not access any other power supply.
tandard power output, you must first select
the output voltage and phase, power loss
Out of the maximum 120% of the theoretical
value.
In this equipment and other equipment shall
disconnect all power devices connected before communication, however electrical
connections cause damage to the equipment.
When DC output 5A 25A, please raise the
current to 100%, preheat five to ten minutes.
