APPENDIXA
Torque Module Calibration
A-8
While installing the calibration weights, you should notice the Torque Gauge on the
DynoTrac Window moving from 0 to about 500 foot-pounds. The gauge is for display
purposes only and may not read correctly. The gauge remains uncalibrated until the
calibration process is complete.
• If the torque cell has been previously calibrated incorrectly or has not been
calibrated for a while, the gauge may show values out of this range until
calibration is complete.
• If you use the bolt pattern in the center of the calibration arm, the gauge will
show values around 250-260 foot-pounds.
Note: Let the torque gauge needle stabilize before clicking Next.
