☆ Metrology Performance Test |
|
☆ Power Supply Impact Test And Power Consumption Measurement |
Built-in DC ±(5.0 V ~ 50.0 V) adjustable power supply, which can test the power supply impact of the sensor under test.
A standard ammeter is connected in series to the power supply module loop to measure the no-load or full-load power consumption of the sensor under test. |
☆ Sensor Bandwidth Test (Optional) |
|
☆ Sensor Response Time Test (Optional) |
|
☆ Direct Display of Sensor Measurement Errors |
Advantages of the solution: The interface of the device can display the primary current output value, secondary signal measurement value, and directly display the basic error of the sensor under test and other measurement results to improve testing efficiency. |
☆Special Test Software (Optional) |
