After you've finished the sensor assignment and installed the sensors, you must calibrate the system. You can either
calibrate the system manually or automatically.
Important: Check the units of measurement that are set in the user menu before calibration: meter [M], feet [F], or
feet & inches [FI]. Change them now if necessary. If you don't, and are partway through calibration and leave the
screen to change the units, all your calibration data will be lost!
Note: Avoid low frequencies from the machine's engine or heavy vibrations, which can cause major inaccuracies
during calibration due to sensor instability. An idling machine is the worst -- run at half throttle (half RPM). You can
check the stability of the sensors any time in "Sensor Check" on page 92. Values shouldn't jump more than 10 digits.
Automatic Calibration (EZCalibration):
These three procedures must be done in this exact order:
1) Dog Bone Calibration (if the bucket sensor is installed to the dog bone).
You need to temporarily use the boom 1 sensor for this.
2) Booms/Bucket Sensors Calibration
A self-leveling laser pointer or rotational laser is very helpful.
3) Laser Receiver Calibration
You'll need a horizontal rotational laser and a hand detector.
Even if you calibrated the other sensors automatically, you can still calibrate
the laser receiver manually.
Manual Calibration:
Usually the most time-consuming method. You'll need 2 people and tools and instruments.
If you only want to calibrate just a new bucket, manual calibration might be faster than automatic
calibration of the whole system.
Note: After calibration, remember which machine and bucket number you were using. Next time you set up the
system on the same machine, you can use the same machine and bucket number to recall the old settings. By doing
this, you don't have to do a sensor assignment or calibration, and immediately may proceed to operation.
Note: You can check the system's calibration at any time by "rotating" the bucket tip over a certain point. While doing
this, the depth value on the control box shouldn't change more than +/- 1cm (+/- ½ inch).
The automatic calibration procedure was developed by the Institute for
EZDigPro
Industrial Mathematics at the University of Paderborn, Germany.
