The XL-9100T6 DC meter verification device includes a standard
source cabinet and a power meter hanging table body. The cabinet is
placed with a voltage source, a small signal source, a current
source, a main control unit, and an industrial computer display
unit, and can output 0 to 1000V (MAX: 1000V). DC voltage, 0~100A
(MAX: 120A) DC current, 0~5V small signal, realizes the output of
the calibration of the electric energy meter, wherein the voltage
accuracy is 0.02, the current accuracy is 0.02, and the electric
energy accuracy is 0.05. The hanging table body is mainly used for
table position fixing, including the hanging table frame and the
table body, and has six epitopes, which can realize simultaneous
verification of 6 electric energy meters (0~100A).
1. Main features
1) The outer casing is made of special aluminum alloy material,
which is beautiful in appearance, firm in structure, light in
weight and convenient in transportation.
2) Use a dedicated junction box for easy calibration.
3) High-quality linear power amplifier, the output ripple is small
and the stability is good.
4) Multiple protection system with sound and light alarm function,
5) The device has an independent PC and common checkpoint shortcut
keys, which can quickly set up common test parameters during manual
meter checking, making manual checking more convenient.
6) The device has comprehensive test function. It can automatically
complete the project test of active energy, daily timing error and
other items by connecting the port of each meter with the special
7) Fully automatic inspection of the starting, sneaking, and basic
errors of the electric energy meter can be carried out according to
the requirements of the regulations.
8) Direct high current output (0~100A), indirect current (0~5V),
designed according to the specifications of DC energy meter, can be
compatible with various DC meter verification or DC meter
9) The voltage and current can be superimposed with 0~500Hz ripple,
the amplitude of the ripple can be set separately, and the phase
remains in phase.
10) The dedicated photoelectric sampler can collect the LED light
pulse signal of the electronic watch.
11) Dedicated pulse sampling interface with high-voltage isolation
circuit to prevent high-voltage mis-access.
12) The word test can be performed according to the power, time or
13) can display power, voltage, current, ripple and other
14) It has the function of connecting with PC, the special
calibration software is friendly, the calibration is simple and
intuitive, and any checkpoint can be manually added and set, and
the data can be stored and printed.
15) With GPS clock reference, support the daily time error test of
the energy meter.
16) The device is powered by a single-phase power supply, which is
convenient for users.
17) The self-heating effect test can be performed on the tested
table, and the error curve is given.
18) DC meter current positive and negative polarity connection can
be program-controlled switching. When indirect meter access is
convenient, it is necessary to manually short-circuit the
corresponding shunt and voltage short wiring to prevent damage to
the energy meter.
