With its 4-way independent programmable signal output and support for multiple signal types (PWM, PPM, SBUS), the ST8 provides precise analysis and control for various servo applications. This manual provides essential information for the safe and effective operation of your ST8 servo tester.

2. Safety Information

Please read all safety instructions carefully before using the ToolkitRC ST8 Servo Tester.

• Ensure the input voltage is within the specified range of 7.0-28.0V. Exceeding this range can damage the device.
• When connecting servos, ensure the current draw does not exceed the specified limits for each port. For currents higher than 2A, connect to the main output interface.
• For servos requiring voltage higher than 8.4V, connect them to the main output interface, not the S1-S4 signal interfaces.
• Always verify correct polarity when connecting power sources and servos to prevent damage.
• Keep the device away from water, moisture, and extreme temperatures.
• Do not attempt to disassemble or modify the device. Refer all servicing to qualified personnel.

• XT60 Input: For connecting the 7-28V power supply (Max 10A).
• XT60 Output: Main power output (5.0-28.0V, Max 10A). Use this for high current/voltage servos.
• S1-S4 Signal Ports: Individual signal output ports (5.0-8.4V, Max 4A).
• S4 EXT Signal Port: Extended signal port (5.0-8.4V, Max 4A).
• S5 Signal Port: Input for PWM/PPM/SBUS signals.
• MicroUSB 3.0: For firmware updates.
• P1 Knobs: For adjusting parameters (1000-2000us).
• OK Button: Used for confirmation and long-press for system settings.
• EXIT Button: Used to exit menus or stop testing.

6. Setup

Follow these steps to set up your ToolkitRC ST8 Servo Tester:

1. Connect Power Supply: Connect a 7-28V DC power supply to the XT60 Input port. Ensure correct polarity.
2. Power On: After connecting power, the LCD screen will display the ToolkitRC logo for approximately 2 seconds, accompanied by a startup sound.
3. Connect Servos:
   • For standard servos (up to 2A current, up to 8.4V), connect them to the S1-S4 signal ports.
   • For high current (over 2A) or high voltage (over 8.4V) servos, connect them to the main XT60 Output port for power, and their signal wire to the appropriate S1-S4 signal port.

7. Operating Instructions

The ST8 offers various testing modes and settings. Here are the basic operating steps:

1. Initial Test (PWM Signal): After power-on, press the "EXIT" button to enter the PWM signal test mode.
2. Channel Selection: Rotate the "OK" button (knob) to select different channels (S1-S4, S5). Press "OK" to confirm your selection.
3. Adjusting Parameters: Use the P1 knob to adjust signal parameters (e.g., pulse width for PWM).
4. System Settings: To access system settings, long-press the "OK" button for 2 seconds. This menu allows you to configure options like voltage output, cycle count, language, and theme style.
5. Exiting Settings: Press the "EXIT" button to leave the system settings menu.
6. Signal Type Selection (S5 Port): When using the S5 port, the device supports PWM, PPM, and SBUS signal types. The display will indicate the active signal type.
