Low Torque
High Torque
Backlight color indentifies high and low Torque Loads
Changes in torque are not only shown with a meter, but can also be identified by a change in the color of the backlight. As torque increases, the color of the backlight changes from blue to green to red so that you can get a general reading with a quick glance. Also, the backlight flashes when torque reaches the set level.
Backlight color distinguishes types of displays
Display changes color: When linked to Root ZX mini, the display changes depending on the location of the file tip inside the canal to warn you and promote safe instrumentation.
The meter for file tip location appears in the display when the file is inserted in the canal. The meter moves along with the file tip to indicate its location inside the canal.
When the file reaches the apical region, the color of the display changes to green.
If the file tip goes beyond the apex, the color of the display changes to red.
