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.
Press the P/C button lightly to turn on the device. If the battery is insufficient after power-on, it will automatically shut down; replace the batteries for normal operation.
In the power-on state (outside the settings interface), press the U/S button to switch seamlessly between the four engineering units (N.m, kgf.cm, ft.lbf, in.lbf).
In the power-on state with no torque applied, press the M button to switch among the three available modes:
The screen displays current torque values in real time as force is applied. Upon unloading torque, the value automatically returns to zero. Indicated by the "T" icon on screen.
The screen locks and flashes the maximum torque value reached during force application. Press the P/C button to clear the peak value, or reapply force directly to update the reading without manual resetting. Indicated by the "P" icon on screen.
Set the target torque value using the Ʌ or V buttons, then press U/S to save and return. As force is applied, torque reading increases/decreases accordingly and returns to 0 when released. Indicated by the "Pre" icon on screen.
What is the measurement accuracy of the GWM Series digital torque wrench?
The GWM Series provides high precision with an accuracy of ±2% clockwise and ±2.5% counterclockwise within 20% to 100% of its total operating range.
Which engineering torque units can be selected?
You can easily switch between 4 standard engineering units: Newton meters (N.m), kilogram-force centimeters (kgf.cm), foot-pounds (ft.lbf), and inch-pounds (in.lbf) by pressing the U/S button.
How does the target torque notification system work?
In Peak Mode, both a buzzer sound and an integrated LED indicator light activate when your predetermined torque target value is reached.
How many torque measurement records can be stored?
The wrench features an internal memory capacity capable of saving up to 999 sets of torque data for tracking and quality assurance.
What battery does the GWM Series use and does it have auto-shutdown?
The unit is powered by 2 standard AAA (7#) batteries. To conserve power, it automatically shuts off after 3 minutes without operation.
How frequently should the digital torque wrench be calibrated?
To ensure continuous precision and compliance with operational standards, regular calibration once a year is recommended using the middle groove of the handle as the calibration point.
