INSTRUMENT CALIBRATION
This section details calibration procedures. If this system has been calibrated by a HELM Field Service
Engineer or by the machine manufacturer, the calibration numbers will be noted on a tag inside the
instrument. Once calibrated, it is not necessary to re-calibrate unless the machine is moved, dismantled or
otherwise structurally changed. If you have any questions or need a HELM Field Engineer for calibration,
please contact our Field Service Department at 419-893-4356.
The illustration below details the locations of switches and potentiometers used during calibration.
