RT9605 DC Resistance Box Test Special Constant Current Source

Description: The RT9605 DC resistor box test dedicated constant current source (referred to as constant current source) is an auxiliary power supply and conversion switch used for precision testing of DC resistors. The combination of a constant current source, high-precision digital voltmeter, computer, and testing software can be used to calibrate DC resistance boxes, DC bridges, and standard resistors. Changed the traditional manual step-by-step balancing measurement method, improved work efficiency, and provided a reliable means of data collection for semi-automatic and automatic testing technologies.


Main technical parameters:

Range	Stability
1mA、10mA	1ppm Imax
0.1mA、100mA	2ppm Imax

A. Usage environment: Temperature 20 ℃± 2 ℃, relative humidity 25%~75%
A dust-free and non corrosive gas environment.
The power supply voltage is 220V ± 10%, 50Hz ± 5%.  
B. Technical performance of constant current source:
There are four ranges of measurement: 10-1, 1, 10, and 100mA.
The effective adjustment range for each range is (0.999-1.001) Imax (Imax - nominal value of each range).
⑶ Fineness of current regulation: 0.2ppm Imax.  
The maximum voltage value of each range load is ≥ 20V.
⑸ Current stability (10min): ⑹ Load characteristics: The current changes caused by load changes in each range do not exceed the current stability index.
