4. Operating Instructions

4.1 Power On/Off

Press the 'C' button to power the wrench on or off.

4.2 Unit Selection

The wrench supports multiple measurement units. Press the 'U' button to cycle through N·m, lb·ft, lb·in, kg·cm, and kg·m to select your desired unit.

4.3 Mode Selection (Peak/Track)

Press the 'P/T' button to switch between Peak Mode and Track Mode:

• Peak Mode: Displays and locks the maximum torque value applied during a fastening operation. Ideal for critical bolts where the highest applied torque needs to be recorded.
• Track Mode: Shows real-time torque values as force is applied. Useful for monitoring torque adjustments in real-time, such as during bike tuning or electronics assembly.
