3. Applications
☆ Detection of DC shunt |
|
• Supports standard source method calibration and testing of DC shunts. • Built-in precision DC voltmeter to measure the output voltage value of the shunt. • Support docking with the user's automated test system (or customized software) to achieve automatic testing. |
☆ Detect current sensor |
|
• The standard source method is used to calibrate and measure the current sensor. • The user can choose the sensor test fixture to measure the power supply and secondary signal of the sensor. • Support docking with the user's automated test system (or customized software) to achieve automatic testing. |
4. Characteristics
☆ High stability |
|
• 24-hour stability typical: 0.003 % (class 0.01), 0.005 % (class 0.02). • It can effectively ensure good repeatability and consistency of sensor and shunt detection. |
☆ Low ripple content |
|
• The current ripple content of the instrument is less than 0.5 %, which can effectively reduce noise interference and ensure the accuracy of test results and avoids surge voltage or current caused by strong ripple to ensure the safety of equipment operation. |
☆ Module source combination output |
|
• The instrument supports DC high-current output in combination mode of multiple module sources, up to 15 kA; • The instrument supports adjusting multiple source outputs, improving the current sharing coefficient, and ensuring stability and accuracy under high-current output. |
