The smart memory function automatically retains your last selected "mode" and "unit" settings, even after you replace the coin cell batteries. Additionally, it features a unique counter function that records the number of times the adapter has successfully reached the target torque (displays up to 999K times), allowing you to easily track the tool's usage history.
Designed for durability and efficiency, the LCD display will show "999" and a high-frequency buzzer will sound if the applied torque exceeds 120% of the maximum torque, protecting the tool from damage. Powered by two CR2032 coin cells, the device includes an Auto Power Off feature that shuts down automatically after 60 seconds of no use to preserve battery life. It is available in 3/8 (ARM602-3) or 1/2 (ARM602-4, ARM602-4A) square drives.
