After entering Angle mode by pressing the UNIT
button and selecting your
desired units, you may start to use the angle function. When you apply the angle,
the wrench will only calculate angle degrees as the applied torque achieves 5% of
the full-scale of the torque wrench. The LCD display shows the actual applied angle
degrees. After applying angle degrees, the degree is displayed, and the display will
flash “maintain 10 seconds. The degrees can be continuously applied until reaching
the set target angle degrees. If the applied angle degrees do not reach the setting
values, the final values you apply will display the accumulated angle until clear by
pressing CLEAR or after 10 seconds to revert back to preset.
Once powered on, you may begin using the torque wrench. After force has been
applied, the LCD will display the actual torque value. Under Peak Mode, when the set
value is not reached, the LCD will display the last torque value attained. The last
reading will flash 10 seconds, but will stop flashing if additional force is applied. If the
torque value is exceeded, the peak torque will flash for 10 seconds then the LCD will
return to display the set torque value. If the torque value equals the set value, a
vibration and buzzer will automatically function.

Angle Mode, then start angle function (the angle preset value must be set in Angle Mode

- If you do not want to wait 10 seconds for the
applied values to reset, you may press CLEAR to force the system to clear the
applied values and return back to the Present Value Display. This same function
can be applied in “Angle Mode” or “T then A Mode."
If the applied torque values or angle degrees reach 100% of the set values, the
vibration and buzzer will act. If more than 104% of the set value is applied, the red
LED lights will flash. As the applied torque values or angle degrees reach the set
values, the lights illuminate to represent the percentage of applied value range
achieved.

To maintain Peak Torque, hold the Peak Torque 10 seconds, LCD will
flash and save into memory.
When releasing forced torque, the LCD will show real-time torque value and keep
flashing 10 seconds then the value will be recorded into memory.
The real-time value will display on LCD. If you release force, the torque value will not
be shown on LCD and not be saved into memory data.
When you are working in Peak Mode or Angle Mode measurement, the value will be
