Item | Description |
| Current Source, Output AC\DC current. |
| Copper Ring 1, I≤100 A(AC). |
| Copper Ring 2, I>100 A(AC). |
| 50T Coil, used to calibrate the DC Clamp meters by amplifing the DC current. |
| Wiring Panel, integrates the output terminals, power switchs and e-stop. |
| Operate Panel, adjust electric parameter of the device. |
| Workbench, Used to settle the device. |
5. Characteristics
☆ Convenient Traceability |
|
| • Calibrate the AC current source through accessing the standard ammeter (TH0630 Precision Through Core AC Ammeter) to the current loop. |
☆Wide Output Range |
|
☆ Output and Adjustment |
|
| • “Direct output”mode: the value output can be set directly by clicking the touch panel. |
|
| • Calibration of the analog pointer meter usually needs to test scale by scale, especially "differences between rising and falling" (the change caused by the rise and fall of the calibration point). |
