Change the speed ratio from 3.36 to 3.7. How to adjust the speed?

1. Through dial code adjustment, the instrument can read dial code data by changing dial code combination in the main engine factory or repair shop, and then match the speed ratio.

2. Change the internal speed ratio of the program through on-site programming to match the speed ratio with the body configuration. However, field programming needs to increase external equipment and manpower to complete, which increases the cost and limits the efficiency.
