☆ Easy to Operate |
|
|
☆ Multiple output\adjustment methods |
|
• “Direct output” mode: the value output can be set directly by physical key or touch screen. |
☆ Multiple output\adjustment methods |
|
• “Rotary Knob” mode, User can set in clockwise direction or anticlockwise direction. |
|
• Use the key ↑10%、↓10%、± 10、÷ 10 on the front panel, can realize the adjustment of the quantity value, and can also be used to perform the relevant test of linearity. |
☆ Special Test Software (optional) |
|
(Note: During automatic calibration, the tested equipment should have communication function and open communication protocol to realize data reading) |
