Setting Frequency Characteristic N-0 Compensation Values of Detector
Despite shaft rotation in the no-load condition, a number may be displayed in the torque display
depending on the frequency characteristic of the detector and display, and the friction torque of the
detector. N-0 compensation corrects this kind of error to enable accurate measurement.
Compensation value for each rpm is specified for up to 10 points. Corrected torque values are displayed
and output at the time of measurement of rpms less than the specified highest rpm.
Although it is necessary to perform N-0 compensation to cancel air friction of the equipment under test
and the friction torque of the bearing, etc., this compensation is performed only when there is
reproducibility. When deviation is sufficiently small, there is no necessity for compensation.
When entering N-0 compensation values, compensation may be performed from the no-load characteristic
table in the Inspection Result supplied with the torque detector. However, when measuring the load
torque using a small torque detector (MD type), it is necessary to take check data instead of using the
values in the Inspection Result. For details, refer to the instruction manual of the small torque detector.
• ON/OFF function
It is possible to select whether or not to perform N-0 compensation.
When ON, N-0 compensation is performed with the specified values.
When OFF, N-0 compensation is not performed even if N-0 compensation values are specified.
• Manual setting (MANU)
MANU: Compensation values are entered separately for up to 10 points. This setting is used when
automatic setting cannot be performed or when fine compensation is required partially.
• Automatic setting (AUTO)
AUTO: N-0 compensation is performed by taking compensation values automatically for up to 10 points.
However, it is necessary to rotate the shaft actually up to the rpm specified by REVO CAPACITY.
• Clearing N-0 compensation value (CLR)
All the specified N-0 compensation values are cleared.
