e, \"Real-time curve \": display the real-time test force value in a curve mode. Press \"Real-time curve \", it will enter \"Real-time curve \" interface, as shown below:

Picture 10.png

\"Cursor force value \": It is the force value at any point on the curve, (click the curve to point, \"cursor force value \" will display the value).

\"Clear \": Press \"Clear\" to clear the peak value of the curve.

\"Clear Curve \": Clear the curve on the screen. (The curve will not be cleared by pressing this key after pressing \"curve magnification \". You need to double-click the screen to restore the curve to the normal size, and then press this key to clear the curve).

\"Peak valley clear \": Clear the value of \"curve valley \" or \"curve peak \" displayed at the bottom of the screen (the value of \"curve peak \" is cleared when measuring peak value, and cleared when measuring valley value \"Curve Valley Value\".

\"Curve Sampling \": Let the force value be displayed in the form of a curve, click to start the curve force value display, and then click to pause.

4. Please do not open the cover behind the display, let alone adjust the trimming resistor inside.

5. Do not loosen the fixing screws of the torque test head.

6. Please use the matching power adapter to charge, otherwise it will cause circuit failure and even fire.

7. Insert the AC power adapter completely into the socket before use. Loose plug may cause a short circuit and cause electric shock or fire.

8. Do not use any power source other than the rated voltage of the power adapter, otherwise it may cause electric shock or fire.

9. Please do not pull out or insert the plug with wet hands, otherwise it may cause electric shock.

10. Please clean the machine with a soft cloth, immerse the dry cloth in the water soaked with detergent, wring it out and remove the dust and dirt. Do not use chemicals that emit easily, such as volatile agents, thinners, alcohol, etc.
