The Precision Level app is used together with the E290 Digital Precision Level. With this app your phone becomes a handy display unit which you can read off at the precise point where you adjust the machine. Climbing up and down on the machine several times to check the precision level value can now be reduced significantly. Available for iPhone, iPad and iPod touch.
The E290 precision level has a clear OLED display with large figures and graphical indication of the angle direction. The value can be zeroed and halved.
