Put a precision test bar [2] into the spindle. Put the tip of the indicator directly below the gauge line to measure runout. The TIR at the gauge line must not exceed 0.0005" (0.013 mm). Put the tip of the indicator against the test bar approximately 6.0"(150 mm) below the gauge line to measure runout.
