3. 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.
The equipment must always be calibrated before using for the first time or after replacing a torque
transducer.
When calibrating the equipment before using for the first time, calibrate by entering the numerical
values, referring to the calibration certificate sheet provided when the torque transducer was
purchased.
When calibrating the equipment after replacing a torque transducer, calibrate by entering the
numerical values, referring to the calibration certificate sheet provided with the torque transducer
purchased.
3-1. Settings Required for Calibration
(1) Minimum 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.
(2) SPAN value
The maximum torque value that can be measured by the torque transducer.
(3) 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.
(4) 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.
(5) Calibration data selection
The 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
jointly calibrated at Minebea, the calibration data will be stored to [Calibration Data 1].
3-2. Settings to be Altered As Necessary After Calibration
For details of the setting instructions, refer to Instruction Manual EN294-1596*.
(1) Symmetry correction
This function corrects torsional span errors in the clockwise and counter-clockwise directions.
(2) Linearization correction
This function minimizes measuring errors by correcting up to five points, excluding zero and span.
(3) Change polarity
This function inverts the polarity of the torque transducer output.
(4) Decimal place
Sets the decimal place for the torque reading on the equipment.
(5) Units
Adds units to the torque reading on the equipment.
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.

Select the minimum torque units.
Set the maximum torque value that can be measured by the

Calibrate the zero point with the torque transducer at the initial
torque state or by setting the zero point torque for the torque

transducer or by setting the span point torque for the torque
transducer.
Calibration is complete. Perform steps 10 onward as described
below where necessary.
Steps 4 to 9 must be carried out in sequence. The calibration results will not be updated if the procedure is not
completed up to step 9.
The A/Z function is canceled once calibration is completed (up to step 9).
The A/Z function is canceled if step 10, 11, or 12 is performed.
