CALIBRATION SCHEDULE
The Troxler Model 4140 Gyratory Compactor is calibrated at the
factory. The compactor requires no initial angle or pressure
calibration upon receipt.
Troxler recommends the following user verification/calibration
schedule for the Model 4140. If calibrating the height, angle, and
pressure, calibrate the pressure first. Then, calibrate the angle of
gyration. Calibrate the specimen height last.
HEIGHT CALIBRATION (see page 3-6)
✓ Calibrate the specimen height daily.
✓ Calibrate the specimen height after changing the consolidation
pressure.
ANGLE VERIFICATION/CALIBRATION (see page 3-8)
✓ Verify the angle every 480 hours or every 6 months. If the angle
of calibration is not within specifications, recalibrate the angle.
✓ Verify the angle after changing the pressure. If the angle of
calibration is not within user specifications, recalibrate the
angle.
✓ Verify the angle after moving the adjustable angle stop.
PRESSURE VERIFICATION/CALIBRATION (see page 3-3)
After calibrating the pressure, calibrate the specimen height and
angle of gyration.
✓ Verify the consolidation pressure every 480 hours or every 6
months. If the pressure is not within user specifications,
recalibrate the pressure.
