Calibration
Calibration refers to the process of adjusting the display reading to match the torque acting on the
torque transducer in order to ensure that the electrical signal from the torque transducer is
displayed as an accurate torque figure.
For example, this adjustment ensures that an accurate reading of 1000.0 N·m is given when a
torque of 1,000 N·m acts on the torque transducer.
Settings Required for Calibration
MIN. SCALE DIVISION
The minimum measurement interval. The available settings are [1], [2], [5], and [10].
The value set for [SPAN value/MIN. SCALE DIVISION] will form the display resolution.
SPAN value
The maximum torque value that can be measured by the torque transducer
ZERO calibration
The setting to be calibrated to ensure that the equipment torque reading is zero when no torque is
applied to the torque transducer (initial torque state). This can be calibrated either using the torque
value (initial torque state) or by entering the torque transducer output value.
SPAN calibration
The setting to be calibrated to ensure that the variations in the electrical signal from the torque
transducer are displayed on the equipment correctly as the torque when a torque is applied to the
torque transducer. This can be calibrated either using the torque value (span torque state) or by
entering the torque transducer output value.
Calibration data selection
This equipment can save up to four sets of calibration data. Select the location for saving the
calibration data by selecting Calibration Data 1 to 4 before calibrating using F-59. If the equipment is
calibrated during assembly, the calibration data will be stored to "Calibration Data 1".
Settings to be Altered As Necessary After Calibration
Symmetry correction
This function corrects torsional span errors in the clockwise and counter-clockwise directions.
See "4-6. Symmetry Correction Function".
Linearization correction
This function minimizes measuring errors by correcting up to five points, excluding zero and span.
See "4-7. Linearization Correction Function".
Polarity change
This function inverts the polarity of the torque transducer output.
See "4-8. Polarity Changing Function".
Decimal place
Sets the decimal place for the torque reading on the equipment.
See "4-9. Decimal Place Setting".
Units
Adds units to the torque reading on the equipment.
See "4-10. Units Setting".
Recalibrate as necessary if the usage environment changes.
The maximum readout resolution for valid performance is 10 000.
In span calibration, use a value of at least 2/3 of the span to minimize calibration errors.
