The meter is activated when the file is inserted into a root canal. The number of bars remaining before the file reaches the flash bar is shown in the lower left corner of the display. |
When the file tip reaches a position near the apex, the bar color changes to green to indicate you have reached a critical area. |
The small triangle on the right side of the meter indicates the point set for reference. |
The position for the apex is represented by the word “APEX”. The meter bars in this area are pink. |
