Magtrol Model DSP6000 Dynamometer Controller
Chapter 6 - Calibration
8. Remove the weight for ZERO adjustment.
9. Press the ZERO button.
10. Adjust the Increase/Decrease Dial until the display
indicates 0 mVDC.
NOTE: The mV output of the
dynamometer will be equivalent
to the Full Scale Torque Rating,
disregarding any decimal point.
Example:
Magtrol’s HD-400-6 Dynamometer has a full-
scale torque of 40.0 oz.in. The distance from
the center of the dynamometer shaft to the pin
on the calibration beam is 5 inches. Placing an
8 oz. weight on the pin will produce a torque of
40.0 oz.in. The mV output of the dynamometer
will be 40.0 minus decimal point or 400.
11. Repeat steps 5 through 10.
12. After completing calibration:
• Press the BRAKE ON/OFF button OFF to
remove loading from the dynamometer.
13. Remove the calibration beam from the
dynamometer shaft.
14. Proceed with your desired motor testing.
Be sure the shaft flat is facing down,
tighten the cal-beam screw against the
shaft flat only.
Torque = Weight (W) x Distance (D)
Weight (W) = Torque / Distance (D)
