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 there for 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 inclinometers two retaining screws and pivoting the
inclinometer until it repeats when level is rotated 180 degrees.
Example: level reads 0.05 to the left, when rotated 180 degrees to the right it should read minus 0.05.
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 levels 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 .05 degrees, and for forming three
angle seats is plus or minus .05 degrees.
