Principle
The digital torque meter adopts electronic Sensor technology for torque measurement, and collects torque data in real time by clamping the workpiece with a locking drill chuck. The instrument converts the torque signal into an electrical signal through the High Accuracy Sensor, and displays it on the LCD screen after processing, and can perform data analytics and storage through the upper computer software.
Applications
Mass inspection, physical experiment, engineering test
Steps
1. Use the locking chuck to hold the workpiece
2. Select the test mode (real-time torque tracking mode, peak hold mode or first peak mode)
3. Set parameters such as unit, upper and lower limit comparison value, peak retention time, etc
4. Perform torque test
5. Review test results and pass judgment
6. Connect the host computer software for data storage, analysis, and report generation
Notice
• operation temperature range is 0~ 40 ℃
• Storage temperature range -20 ℃ -70 ℃
• relative humidity range of 15% -80%
• The working environment should be free of vibration and corrosive media
• Power frequency AC 220V 50HZ
• Clamping range is φ 1.5-φ 10 mm
• Be careful to set the gravitational acceleration value correctly
Periodic instrument calibration to ensure measurement accuracy
