Calibration
SMCS - 7610-524-MCH
Using Caterpillar Electronic Technician
The Caterpillar Electronic Technician service tool is used in order to access the calibration procedures. For
more information, refer to the manual that was provided with the ET.
Similar procedures for calibration may also be performed through the Monitoring System. See Systems
Operation, RENR8068, "Calibration Mode".
The calibration menu is used in order to compensate for the differences in the mechanical components and
the electrical components. The calibration should be performed if the ECM has been replaced or the ECM
was removed. The calibration should be performed if components have been replaced or removed. Perform
all calibrations that are applicable.
Note: Be sure the hydraulic oil temperature is at least 50 °C (122 °F) before performing calibrations.
Accessing Calibrations
Connect the ET to the machine. See Illustration 1. After communication has been established, the ET will
list the electronic control modules that are on the machine.

Note: The ECM must detect specific set-up conditions before beginning the calibration procedure. If a set-
up step is not met, the calibration procedure is aborted.
1. Select the Machine ECM.
