Magtrol WB/PB DynamometersChapter 6 – Calibration
Caution: for overload Calibration of wb/pb 43, 65 and 115 series
dynamometers, readings of 150% of the nominal torque are only
possible if the measuring system operates without saturation.
with a Complete dsp-Controlled magtrol system (wb/pb
dynamometer, dsp dynamometer Controller, des power
supply and tsC torque/speed Conditioner), the tsC unit must
be ConneCted to the tsC2 input of the dsp unit (as the tsC1
input Cannot measure a value of more than 130% of the nominal
torque).

1. Mount the calibration arms. (See Section 6.1.1 – Calibration Arms.)
2. Place 100% of the calibration weight on the arm on the connector side.
3. Adjust the screw
 to decrease the torque slightly.
4. Place 200% of the calibration weight on the arm on the connector side.
5. Adjust the screw
 so that the display indicates 150% of the nominal torque.
6. Move the 100% calibration weight onto the opposite arm.
7.
Adjust the screw  to decrease the torque slightly.
8. Place 200% of the calibration weight on the arm.
9.
Adjust the screw  so that the display indicates 150% of the nominal torque.
10. Remove the calibration weight and arms.
