TD4500 AC Sampling and Transmitter Testing System

TD4500 is a multifunctional instrument used for calibrating power/electrical measuring instruments. Integrating multiple standard sources and measurement functions, with two optional specifications of 0.02 level/0.05 level, it can perform virtual load or real load calibration on AC sampling devices in power systems, and is also suitable for calibrating three-phase DC measuring instruments, power transmitters, same cycle meters, etc.

TD4500 AC Sampling and Transmitter Testing SystemFeatures

Graphic and intuitive display

It has waveform display function and phasor graph to display phase, and reflects short-term trend through point graph.

Harmonic loading function

Harmonic amplitude and phase can be set to display the synthesized harmonic waveform or spectrum.

Professional testing software (optional)

Optional automatic calibration software can be used to adapt to various electrical measuring instruments. Refer to the JJG124-2005 Verification Regulations for Ammeters, Voltmeters, Power Meters, and Resistance Meters, JJF 1587-2016 Calibration Specification for Digital Multimeters, and other regulations for automatic testing requirements, and automatically generate testing reports to improve testing efficiency.

Fixed point output

The instrument has a "fixed-point output" mode, which allows you to directly set the desired output value through the digital buttons on the front panel or by clicking the touch screen. The instrument will automatically switch to the optimal range output, making it very convenient to calibrate digital instruments.

Percentage verification point

Users can easily select the calibration point of the tested meter through the "percentage calibration point" on the touch screen of this instrument.

Remote control adjustment box (optional)

We provide users with a remote control adjustment box (optional accessory), which can quickly adjust the output to align with the scale of the tested meter through rough adjustment and fine adjustment, making it very convenient to complete the calibration of the analog meter. This function is particularly important when considering friction or hysteresis effects during movement.

rotary encoder

The operation area is equipped with a "rotary encoder" that can increase or decrease the output of small values by rotating clockwise or counterclockwise.
