TH3422 多通道数字功率计

TH3411/TH3421/TH3422 is the use of professional phase-locked loop frequency doubling synchronization technology, multi-channel synchronization source signals can be selected, equipped with an embedded operating system, making the human-computer interaction interface is more flexible and stable, and its (0.15% readings + 0.2% range + 1 word) the basic accuracy of the test, the conventional test 7 times the speed of the test, DC/45Hz- 420Hz frequency range can meet most of the power system measurement requirements in the market, standard with harmonic analysis function, for industrial frequency signals can test the maximum 50th harmonic components.

Supports rich external interfaces, for RS232/RS485 serial communication, provides standard SCPI command parsing and ModBus command parsing protocol optional, which greatly enriches the programming needs of automation system.

The comparison output functions provided provide a powerful tool for design, inspection, quality control and production testing of a wide range of source and load devices.

The simple waveform display and vector graph display can effectively assist in analyzing the characteristics and abnormalities of the input signal.

U-disk recording of test data for easy statistical analysis of test results.

Functional Features

A. Free display of multi-channel tests

B. Flexible test parameters for the main test page

Double-click the corresponding display area to bring up the setting menu.

C. Comparative functions

Comparison outputs for 8 comparison channels with programmable output methods;

The simple and intuitive comparison display makes the comparison results clear at a glance and shows the current relay switching status of the corresponding output interface;

The comparison parameters for each comparison channel can be set arbitrarily.

D. Harmonic analysis

The analysis parameters are controllable, providing list display and bar graph display.

E. Waveform display

Provides waveform display functions for basic input signals and waveform display for integrated power.

F. Vector display

Provides a vector diagram display of the input signal, which can visualize the symmetry relationship of the input signal and the information related to the size of the phase offset.

G. Help system

The more extensive help system is a good way to help users familiarize themselves with this machine.

If you select the wire system combination, there is a wire system corresponding to the schematic wiring diagram, you can directly to the wiring can be, free of wiring trouble;

The help system embedded in the instrument can pop up the help information of the specified chapter by long-pressing the button control that needs help when it is needed for operation, and it can also be opened directly under the toolbar set by the system, and browsed freely according to the index of the catalog.

H. Software upgrades

Provides flexible software upgrade control, which makes the post maintenance of software stable and reliable.
