Jaw Pressure & Springs
The general rule of thumb for the effective lifespan of the springs is 5 years, although it depends on how much the caliper is used. Over time, the jaw pressure will be reduced. The speed at which that happens depends on how many times the lever is exerted ("cycles"). After 10,000 cycles, the pressure will be reduced by 10%. The technician should keep track of estimated yearly use.
While spring replacement is not currently available, it will likely be available by early 2026.
