Product Introduction

The TD4200 with a 0.01 level is built on the basis of a highly stable three-phase standard source, using the TD3310 three-phase multifunctional standard meter (0.01 level) developed by Tianheng Measurement and Control as the AC power sourceThe reference benchmark for flow values and the tool for ensuring accuracy are immediately sent for inspection to complete the traceability of measurement values. If using a three-phase standard table with a 0.01 level inlet (such as COM3003, RD33, K2006),The software and hardware of the device are compatible with these standard tables, and can control and read data from the standard tables to complete automatic verification and calibration work.

◉ Standard table selection suggestion: The maximum output voltage of UAN, UBN, and UCN of this device can reach 825V, and the maximum output voltage of UAB, UAC, and UCB can reach 1500V. When selecting the standard table configuration, use ⼾Should be able to maintain the above voltage values.

Main application (0.01 level)

◉ Verify or calibrate single/three-phase AC voltmeters, ammeters, voltage sources, current sources, etc. with a rating of 0.02 or below
◉ Verify or calibrate single/three-phase AC power meters and power sources with a level of 0.05 or below
◉ Verify or calibrate DC voltmeters and ammeters with a rating of 0.05 or below, and DC power meters with a rating of 0.1 or below
◉ Verify or calibrate various frequency meters, phase meters, power factor meters, AC/DC transmitters, etc

Functional Features

◉ Three phase power output and measurement: voltage up to 825 V, current up to 120 A, and current output at a minimum of 0.1 mA.
There are two sets of independent output and measurement terminals on the calibration table, which can be switched through software to achieve "source calibration table" or "meter calibration source".
Harmonic output function: The three-phase output can load harmonics with adjustable amplitude and phase from 2 to 21 times, and conduct harmonic impact tests on the tested meter.
Harmonic measurement function: Three phase transmission can measure 2-64 harmonics, analyze the content of each harmonic and total harmonic distortion of the detected source.
The source output has strong load capacity and can cover the calibration and verification of pointer instruments such as electric systems.
All sources, meters, terminal knobs, and communication ports are designed with modularity for easy disassembly and inspection.
The calibration table is equipped with a control panel, which can be used to observe or control the output of measurement values through its LCD touch screen, and can be manually checked.
◉ DC power output (optional): Voltage up to 1100 V, current up to 110 A, low current up to 1 μ A.
◉ The software maintains communication with the majority of the tested meters/sources, enabling full automatic calibration or verification.
The testing functions include: error and uncertainty calculation, output stability and measurement repeatability analysis, automatic rounding processing, etc., and automatic judgment of whether it is qualified.
◉⽀ Provide data management functions such as printing certificate templates, searching historical data and certificates, and analyzing annual errors.
