Main application (0.01 level)

◉ It can directly verify DC splitters with an accuracy of 0.05 level or below, measure their resistance values, and complete basic error tests.
Four TH0200 DC current ratio standard and two TH0270 reference level high-power standard resistors can be optionally selected for use,
Formulate a set of high current self tracing ratio standards with an uncertainty of 0.5 ppm to 2 ppm, used for verifying high-level current ratio standards, sensors, etc.
This comparison standard can also be used in AC/DC measurement modes (such as DC+AC, etc.) and applied to testing of energy, solar energy, electric vehicles, motors, etc.
Analyze the key parameters such as power coefficient and thermoelectric potential of the DC splitter, and use software to draw the R (I) and R (t) curves of the splitter.

Functional Features

Each current source is equipped with a broadband current comparator for current measurement and control, ensuring high stability and accuracy of the current.
The peak current stability of the 0.01 level device reaches 15 ppm/h, and the differential stability reaches 6 ppm/h.
The computer can independently control each current source and accurately output a DC current of 5 A to 100 kA through software programming.
The high current output is controlled by software to gradually increase and decrease, reducing current surges and avoiding power overshoot on the power supply and the tested resistor.
Equipped with a built-in 7-digit DC voltmeter, capable of measuring up to 11 V with an overload capacity of 50 Vpk, there is no need for an external digital multimeter for voltage measurement.
The current source has safety functions such as current open circuit, overload protection, and error mode recognition, with high reliability.
Capable of working continuously for 24 hours, providing conditions for special products (such as military workers) to undergo continuous testing for more than 72 hours.
Abandoning low-cost but high electromagnetic interference thyristor devices to reduce electrical pollution and maintain the purity of the laboratory electromagnetic environment.
The resistance value of the shunt can be directly read and displayed, and the system efficiency is better than 80%, with good operational economy.
