The calibration was made with Torque Calibration Machine (TCM) as below.
Preload was applied three times on each rotational mounting position of the torque transducer.
However, preloading was conducted one time in the next position when it took shorter than 20
minutes for changing the position.
Torque loadings were made in three mounting positions of 0°, 120°, and 240° in both clockwise
and counterclockwise torque.
The time interval between two successive loading cycles was two minutes.
The reading corresponding to each torque step was noted after waiting 30 seconds after thetorque was applied or removed.
One cycle of incremental and decremental torque and one cycle of only incremental torque weremade in the mounting position of 0°. One cycle of incremental and decremental torque was madein mounting position of 120° and 240°.
The resolution of the indicator itself was 1 000 000 digits for the output of 1.0 mV/V as the rated
output of the torque transducer.
The Cut-off Frequency of the low-pass filter of the indicator was 2 Hz.
The torque transducer was excited with the voltage of DC 10 V.
A six-conductor cable of 5 m length was used for connecting the torque transducer and theindicator.
The torque transducer and the indicator were energized at least one hour before the calibration,and continuously kept energized throughout the calibration.
The ambient conditions of the calibration room were as follows:
22.3 °C
23.1 °C
Temperature:～1007.3 hPa ～1008.5 hPa
Atmospheric pressure:50.5 %

・ The expanded relative uncertainties shown above correspond to a confidence interval of approximately 95% and are
calculated by multiplying the relative composite uncertainly and the coverage factor, k = 2.
・ The interpolative formulae described on page 4 calculated from the measured data can be applied for any values in
the ranges from - 100 N m to -10 N m, and from +10 N m to + 100 N m.
・ The equivalent values of the indicator calibration data were calculated from the interpolation of the incremental data.
・ The expanded relative uncertainty includes the uncertainty of the generating torque of Torque Calibration Machine,
the uncertainty due to the mounting positions, repeatability at the same mounting position, the difference between themeasured value and the interpolation, the zero-deflection between the start and the end, the hysteresis, and thefluctuations of the indication at the respective load steps.

・ The class judgment was made according to JMIF015 (TTSG-103), including the zero error and the hysteresis
calculated using the decremental data.
