Rotary Mouse Operation Guide for Automatic Volt-Ampere Characteristic Tester:
The rotary mouse functions similarly to a computer mouse, with three operations: "rotate left", "rotate right", and "press to select". These three operations can be used to move the cursor, input data, and select operations.
Move cursor: You can move the cursor position by rotating the mouse. When the cursor moves to an option and you need to select it, press the knob to confirm the selection.
Data input: When you need to modify data, move the cursor to the option you want to change, press the mouse, then rotate left or right to increase or decrease the value. Press the mouse to confirm the modification for that option. After modifying all items one by one, press the mouse to confirm.
Instrument Setting Parameters for Automatic Volt-Ampere Characteristic Tester
1. Segment point current value: During the test, to ensure reasonable distribution of points before and after the inflection point of the volt-ampere characteristic curve, a segment point is set. Before and after this point, tests are conducted with two different current step sizes. The segment point current value is set based on estimated value or measured inflection point value, range (0 - 20) A
2. Step size before segment: The step current increment before the segment point, range (0.001 - 2.000) A
3. Step size after segment: The step current increment after the segment point, range (0.001 - 2.000) A
4. Output voltage: The maximum voltage that the secondary side of the current transformer can withstand, range (0 - 2000) V
5. Maximum output current: The maximum current that the secondary side of the current transformer can withstand, range (0 - 20) A
6. Test mode: This instrument has three test modes: standalone test, external booster test, and external voltage regulator test
