Overview
HNJ series digital torque measuring instrument is a Handheld torque measuring instrument, mainly used to detect the tightness of the workpiece and the torsional performance of some parts. The instrument adopts electronic Sensor technology, which has the advantages of high accuracy, easy operation and reliable data. It is equipped with a special host computer operating software to connect to the computer for data storage, analysis, export, query and printing.
Features
1. High Accuracy, high resolution, high stability, sampling speed up to 100HZ
2. Special Instrument Toolbox with EVA Shockproof Encasement, Easy to Transport, Save and Carry
3. Segment LCD display, green backlight screen
4. Three units N.m, kgf.cm, lbf.in automatic conversion
5. Test direction display (counterclockwise +, clockwise -)
6. Three test modes: real-time torque value tracking mode, peak hold mode, first peak mode
7. Can set the upper and lower limit comparison value to judge whether the data is qualified or not, with sound alarm and level signal output
8. Store 99 sets of test data and automatically calculate the average value of the stored data, MAX Maximum and MIN Minimum.
9. Peak hold time can be set (can be set from 0 to 99 seconds)
10. Gravity acceleration value can be set
11. Automatic shutdown without operation can be set (time can be set freely from 0 to 99 minutes)
12. Using intelligent charging, safe charging, prolong battery life
13. Host computer software: Chinese WINDOWS interface
14. Linear dispersion of test results: real-time torque value - time, peak torque value - times, first peak - times
15. Qualification judgment: In addition to automatically obtaining test results, qualified judgment and batch testing pass rate can also be made according to the qualified range of preset standard values
16. Automatic storage: Test data and Linear dispersion are automatically stored in the computer, and the number of storage is unlimited
17. Test data: The data obtained from the test can be queried and exported in excel format
18. Test report: Test report can be prepared in the format required by the user, form a report and print it
Principle
The instrument uses Electronic Sensor technology for torque measurement. The locking drill chuck clamps various rod-shaped or short-sized workpieces to detect the tightness and torsion resistance of the workpiece. The sampling frequency is 100Hz to ensure real-time and accuracy of the data.
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. Conduct torque test, the instrument automatically displays and stores data
5. Connect PC software for data analytics, export and report generation
Notice
• operation temperature range is 0~ 40 ℃, storage temperature is -20 ℃ -70 ℃
• relative humidity should be kept at 15% -80%
• The working environment needs no vibration and corrosive medium around
• Power frequency is AC 220V 50HZ, ensure correct connection
• Regularly check instrument accuracy to avoid over-range use
