20.3.1. Torque sensor (load cell) (channel 2)
*
NOTE This sensor is only present in upgradeable AutoDyn systems using the axle and
differential.
The torque link measures the force created from the absorber
load and from parasitic losses in the axle and sends an analog
voltage to the CPU for conversion and measurement. The
force measured is only as accurate as the calibration that is
performed on the unit. If the calibration is off by five percent,
then the measured power will be off by five percent as well.
The load cell has been pre-calibrated at the factory, but it is
wise to check the calibration periodically. SuperFlow recom-
mends doing this every month.
To calibrate the load cell, perform the following steps:
1. The test system and test room should be at normal operat-
ing temperature. Leave the test system power on for at
least 15 minutes prior to performing a torque calibration.
2. Hang the calibration arm on the load cell. Make sure there
is no weight on the calibration arm at this time.
3. Zero the Roll Torque Channel from the handheld controller
or from WinDyn:
From the handheld controller:
Select “ Autozero ” (F-key) followed by “ Single channel ” (C-key)
Select channel #2 (RolTrq) by pressing “Select” followed by “ 2 ”
and “Enter” . Press “Exit” (E-key) to return to the main menu.
