Precaution1. Do not exceed the rated torque during testing; always operate within the measurement range of the torque tester to avoid instrument damage and potential hazards.
2. Do not tap the LCD screen or place objects on it.
3. Do not press the function keys with fingernails, sharp objects or other pointed items.
4. Do not use the torque tester in areas where water, oil or other liquids may splash; store it in a cool, dry, and vibration-free environment.
5. Do not loosen the fixing screws of the torque test head.
6. Do not use any power source other than that rated for the intended voltage, as this may cause electric shock or fire.
7. Do not insert or remove the plug with wet hands, as this may cause electric shock.
8. Clean the device with a soft cloth by soaking it in water containing cleaning agent, wringing it thoroughly, and then removing dust and dirt. Avoid using volatile chemicals such as essential oils, diluents, or alcohol.
9. Handle with care during use and transportation.
10. Do not disassemble, repair, or modify this device without authorization. Such actions may cause permanent malfunctions to the instrument.
11. In case of a malfunction, please contact the original retailer or our company.
Product Features1. High precision, high resolution, fast sampling speed and large-screen display.
2. Equipped with a high-precision torque sensor featuring directional torque display, and a high-precision rotary encoder for arbitrary angle measurement.
3. You can freely set upper and lower torque limits as well as maximum and minimum rotation angles; if values exceed the preset ranges, text will flash and a buzzer alarm will sound.
4. Three parameters display (torque value, rotation angle and spring stiffness).

6. You can freely switch between three modes: Real-time, Peak and Automatic Peak.
7. Connect the machine to a PC via a USB interface for communication; the synchronous testing function allows connection to a computer for testing, the test torque, angle torque, time curves, angle-time curves are displayed on the computer, along with detailed measurement parameters recorded during testing, which can be saved, printed and analyzed.
8. Peak retention, automatic release function, and customizable release timing.
9. Large storage capacity, capable of storing 99 sets of test data.
10. No automatic shutdown function during operation; time can be set freely.
Operation Panel
The intuitive operation panel features a clear multi-parameter LCD display, one-click functions (peak hold, unit switch and save/print), built-in safety alarms and flexible multi-unit/USB data export for fast, accurate and traceable testing, improving the operation convenience and meeting different testing demands.
Testing Workbench
The precision-machined testing workbench features a high-hardness and anti-rust metal construction for long-lasting durability. The replaceable core shaft design securely fixes various torsion springs without slippage, ensuring accurate torque and angle measurement. The rotary platform allows for stable and jitter-free torsion testing.
Measurement Handwheel
The ergonomic handwheel features a comfortable non-slip grip for smooth and controlled manual loading. It allows precise adjustment of torsion speed and force, eliminating the impact load that affects the test accuracy or damages the spring/sensor. Its durable and lightweight structure ensures long service life and easy operation during repeated testing.
USB Interface
The built-in USB interface enables fast and reliable connection to a PC for real-time data transmission, test result export and report generation. It supports direct saving of torque, angle and stiffness data for traceability, quality control and further analysis, making it easy to integrate with your existing quality management system.
Supporting Feet
The heavy-duty adjustable leveling feet provide stable and anti-slip support for the tester, allowing precise height adjustment to keep the machine perfectly level on the work surfaces. The supporting feet effectively reduce vibration during testing while protecting the tester and the workbench from scratches and damage.
Auxiliaries
The tester comes with a complete set of interchangeable precision core shafts and a high-quality USB data cable. The multi-size core shafts ensure secure and slip-free clamping for various torsion springs and expanding testing versatility. The USB cable enables stable and interference-free data transmission.
Operation Method
1. Under normal conditions, connect the power cord to the 110V power supply and turn on the power switch. Once the display stabilizes, if the displayed value is not zero, press the Reset key to reset both the torque value and its display.
2. On the basis of testing requirements, use the unit conversion key to select the desired unit.
3. Perform the setup before testing; and see the parameter settings interface for detailed steps.
4. Torque testing procedure for torsion springs
(1) According to the testing requirements, select an appropriate core shaft and install it into the positioning hole of the measuring disc. Then mount the spring onto the core shaft, and secure the fixed end of the spring by engaging the positioning groove with triangular blocks or pressure blocks inside the groove for stable fixation.
(2) Adjust the shifting fork on the stand column until it touches the other end of the torsion spring; at the moment of touch, both the force and angle values reset to zero.
(3) The torque and angle values displayed on the LCD screen are zero.
(4) According to the torsion spring measurement requirements, simply rotate the measuring handle smoothly and evenly to display the technical parameters of the tested torsion spring.
(5) Repeat the above procedure to verify the technical parameters of the torsion spring.
