display toα1 with level, when you push “Calibrate”，the display showed
“0”。And change the degree to the next angle α2，the screen will show
the angle number (α2+α1），and then push the button for 3 second ,the number
will be changed to the number α2.
3.Angle display stay a degree α with level, the number will be showed on the
screen accordingly, when you push “HOLD”，αthe number is locked，and the
pointer on both side sparkling, and the button released when you push the
button again .
4.When the angle display is in a degree αless than 450，push “0%”，it display
the number of tgα；If the angle display is in a degree α more than 450，
push “0%”, it display the number of tg（900-α）.
5. The field of the angle measured is 0-900, if you don't push any function
key in 3 second the angle display will stopped.
