Notice:
*1. The accuracy guarantee range is 20% to 100% of the maximum operating value. The torque accuracy is the normal value. The calibration accuracy takes the middle groove of the five grooves on the handle as the calibration point. To ensure accuracy, it is recommended to calibrate it once a year.
*2. "Once" means that the wrench is applied from 0 N.m to the maximum operating setting value of the wrench, and then back to 0 N.m.
Instructions
1. Boot
Press the P/C button lightly to turn on the device. If the battery is insufficient after the device is turned on, it will automatically shut down and it can be used normally after replacing the battery.
2.Unit switch
In the power-on state, when the user interface is not the setting interface, press the U/S button to switch between the four engineering units.
3. Measurement mode conversion
In the power-on state with no power, press the M button to switch modes.
A. Real-time mode
Real-time measurement mode: The torque value will display the current value in real time as the applied torque changes. When the torque is unloaded, the torque value will automatically return to zero. The “T” character displayed on the screen is the real-time mode.
B. Peak mode
The force applied by the wrench will increase from the minimum measured value gradually. When the force is continuously applied, the on-screen torque value will always display the maximum torque value when the user applies a different magnitude of force; when the user unloads the force, the on-screen display will record and lock the maximum torque value during the force application process, which is the peak torque. And this value will be flashing. Press the P/C button to clear the peak torque. Maybe, if it needs to be measured again, the user can reload the applied force to update the locked peak torque without clearing and resetting directly.The “P” character displayed on the screen is the Peak mode.
C. Preset value mode
First, set an ideal preset torque value through the Ʌ or V button, and then press the U/S button lightly to save and return to the measurement interface. The force applied by the wrench will increase from the minimum measured value gradually. When a force is applied, the on-screen torque value will change as the user applies different forces; the reading will increase with the increase of the force, and decrease with the decrease of the force. When the user unloads the force, the on-screen display will return to 0. The “Pre” character displayed on the screen is the preset mode.
