Description:

The Multi Servo Tester with Indicator LED is a compact and portable device that allows you to easily detect and configure the virtual spaces, jitter, and median of servos. It can be connected to up to three servos or electronic speed controllers (ESC), providing good stability and high accuracy with MCU control. This servo tester has a knob for turning and steering detection, allowing you to easily test the speed and performance of your motor without the need for cumbersome remote control devices. It can be used to test tone or for manual speed control of electronic governors (brush or brushless). In addition, the Multi Servo Tester can be used in three modes to check the servos or ESC. The manual mode allows you to turn the knob with different speeds to check the reaction time. The neutral mode makes the servo return to the neutral point, while the automatic "window wiper" mode makes the servo swing like a window wiper in the biggest angle.

 

 

Principle of Work:

The Multi Servo Tester is a device that allows you to test and configure up to three servos or electronic speed controllers (ESCs) at the same time. It is designed to be connected to a power source with a voltage range of 4.8-6V. The device has three different modes of operation: manual mode, neutral mode, and automatic "window wiper" mode. In manual mode, you can turn the knob to test the reaction time of the servos or ESCs. In a neutral mode, you can make the servos return to their neutral position. In automatic mode, the device will cause the servos to swing back and forth in a "window wiper" motion. To use the Multi Servo Tester, connect up to three servos or ESCs to the device. Then connect the device to a power source with the appropriate voltage range. Once the device is powered on, select the mode of operation that you want to use and adjust the settings as needed using the knob.

The Multi Servo Tester is a useful tool for anyone who works with RC models or other devices that use servos or ESCs. It can help you detect and configure virtual spaces, jitter, and median for servos, as well as test and compare the reaction times of multiple servos or ESCs at the same time.

 

Pinout of the Module:

 

• OUT - S: The three-pin column in 3x3 berg is used for three Servo signal out.
• OUT - +: The middle three-pin column in 3x3 berg is used for three Servo signal Power line.
• OUT - -: The three-pin column in 3x3 berg is used for three Servo signal GND.
• IN - S: The Servo Signal Input is used to connect a signal wire from the remote control receiver or the servo tester.
• IN - +: The Servo Power Input is used to connect a power supply wire for the servos.
• IN - -: The Servo GND Input is used to connect the ground wire for the servos.

The connections are used for controlling servos, and the different pins are responsible for specific functions in the process. The IN and OUT pins are used to connect input and output wires to control the servos, while the + and - pins are used to connect power and ground wires.

 

 

Applications: 

1. Testing servo motors: The tester can be used to test the consistency of servo motors.
2. Testing ESCs: It can be used to connect and test up to 3 electronic speed controllers (ESC) to compare their reaction times.
3. CCPM helicopters: The tester can connect to 3 servos of the CCPM (Cyclic Collective Pitch Mixing) helicopter and select servos.
4. Airplanes: The tester can connect to the servo of airplanes, install the steering box and adjust planes by using such as the neutral mode.
5. Motor performance: The tester is useful for testing speed or motor performance, eliminating the need to connect the remote and the receiver.

 

 

Circuit:

 

The Servo Tester has three modes: Automatic, Neutral, and Manual. It has LED indicators to show the current mode. In Manual mode, the adjustable knob rotates the servo motor, and in Neutral mode, the servo motor moves to its neutral position. In Automatic mode, the servo motor rotates automatically.

Testing Steps:

1. Connect the servo motor and power supply.
2. Turn on the power supply and determine the current mode using the LED indicator.
3. In Manual mode, rotate the speed knob to rotate the servo motor.
4. In Neutral mode, press the mode selector switch to move the servo motor to its neutral position.
5. In Automatic mode, press the selector switch to activate the automatic rotation of the servo motor.

Comparisons:

there are other ways to test a servo motor without using a dedicated servo tester. Some alternative methods include:

1. Using a multimeter: By connecting the multimeter probes to the servo motor's signal and ground wires, you can measure the voltage output and monitor changes in response to different positions of the servo horn.
2. Using an Arduino: You can program an Arduino board to send signals to the servo and test its movement, speed, and position accuracy.
3. Manual testing: You can manually move the servo horn to different positions and observe its movement and response to check its functionality.
4. Using a servo signal generator: A servo signal generator can be used to send different signals to the servo motor and check its response.

However, a dedicated servo tester like the one mentioned earlier offers an easy and convenient way to test and adjust servo motors without the need for additional equipment or programming knowledge.
