Calibrating the Digital Level:
NOTE: Even though the level has been carefully calibrated at the
factory, it is a good idea to recheck calibration before putting the
machine into service. In the event that the level is dropped or handled
roughly then the following recalibration methods should be
implemented.
The level assembly is referenced to the spindle via the level pin. It is
important to check alignment of pin in reference to the spindle. This is
accomplished by mounting a magnetic base dial indicator to the
machine spindle and sweeping the pin vertically by raising or lowering
spindle to check alignment. Pin alignment should be checked in two positions
at 90 degrees to each other. If the pin alignment needs correcting, do
so with the set screws located at base of pin block.
Install level on pin. Orient level to read left to right. Tilt head left or right
until level reads 0.00. Now rotate level 180 degrees. The reading
should be 0.00, if not then it will be necessary to calibrate the
inclinometer to the level body. This is accomplished by loosening the
inclimeter’s two retaining screws and pivoting the inclimeter until it
repeats when level is rotated 180 degrees. Example: level reads 0.04
to the left, when rotated 180 degrees to the right it should read minus
0.04.
Check the level reading with the pickup oriented front to back. It should read 0.00 if the machine has been
properly leveled with a machinist level.
If the LED does not read 0.00 then chances are the machine’s leveling procedures have not been properly
followed or there are internal problems with the level’s electronics.
The sensitivity of the level is so great that it may not zero totally, even while the machine is not being
touched. The alignment tolerance for installing guides is plus or minus .04 degrees, and for forming three angle
seats is plus or minus .08 degrees.
