Calibration Procedure
the torque arm of the dynamometer to insure that there is no force being applied to the load cell which would result in an inaccurate zero calibration. Remove the calibration access cover panel and set the calibration mode switch to the ZERO position. Also, be sure that the shunt resistor switch is set to the OFF position. At this time note that the RPM display of the unit should indicate “1111” and the POWER display should indicate “0000”. The TORQUE display indicates the TORQUE and should read near zero. If the torque indication is excessive plus or minus, the POWER display will read “EEEE” - which indicates that the zero offset of the load cell is excessive and that the ZERO calibration cannot proceed see calibration notes below. Otherwise, press and release the ENTER push-button switch to perform the zero calibration. At this point, the TORQUE display should indicate zero and the zero calibration procedure has been completed
positive and negative torque to the unit and verify that the torque reading returns closely to the same value. A failure here indicates a likely problem with the dynamometer. Have the dynamometer checked by your dealer or dyno service person
