Features: 1. Driving Mode: Driving mode is the default when power is turned on. Adjust the knob to change the high level of the output signal. 2. Capture Mode: Press the button and 000 will be displayed as capture mode. When the signal to be tested is connected, the high level will be displayed. 3. The input voltage of the power supply is 5V~12V 4. Signal tester is controlled by a single-chip microprocessor and has two control modes, which can be switched by pressing the button. These are servo control mode and servo capture mode respectively. rudder 5. The machine's driving mode can output a PWM square wave with a high level of 0.5ms~2.5ms and a fixed period of 50Hz, which can be used to drive the servo. Signal capture mode can be used to test the output signals of other servo boards, displaying the high level from 50 to 999, in units of 10us.
