Converted torque (cont.)
[Setting procedure]
Notes about converted torque
data
• Converted torque is only estimation
from the tool's state quantities and
therefore cannot be used for
accurate torque management or
quality recording.
• Conversion requires a specific
amount of variation and therefore
does not support refastening or
momentary fastening.
• The converted torque becomes 0 if
conversion failed.
• Use conversion when fastening at
intervals of 0.2 or more seconds.
• This tool is not a gauge and cannot
be calibrated.
• This system does not support
mapping of serial numbers or such
other unique product numbers.
Notes about the converted torque
setting
• Make settings (adjustments)
beforehand.
• Change the settings whenever you
change the screw or workpiece
material, the clutch step, etc.
• After setting, test and check the
fastening status using an actual
workpiece to confirm the desired
torque is obtained.
• The work conditions and the Electric
Screwdriver conditions change over
time.
Adjust the settings on a regular
basis.

Make preparations.
Depending on the management
method on site, find the clutch step
that generates a torque closest to
the set torque [X].
There are two torque
management methods.
(for details, refer to
)
P. 24
(A) Method that manages the
torque exercised on a screw
fastened to an actual workpiece
(B) Method that manages the
torque of the screwdriver
Collect data.
Try fastening 10 or more screws to
an actual workpiece.
* Always use an actual workpiece
even when you use method (B)
for management.
Make settings.
(1) Calculate the average [X].
(2) Subtract [Y] from [X] to
calculate the difference [Z].
(3) Input [Z] as an offset of torque.
Example 1
Set torque [X]
0.8 Nm
Average of converted
1.04 Nm
torque [Y]
Difference [Z]
-0.24 Nm
Offset
-0.24 Nm
Example 2
Set torque [X]
1.3 Nm
Average of converted
0.98 Nm
torque [Y]
Difference [Z]
0.32 Nm
Offset
0.32 Nm
Rotation
[Functional overview]
You can determine the fastening
status by the rotation (times) of
screw fastening.
Set the lower limit and upper limit
of the rotation (times) that is
judged as Fastening OK.
For the rotation (times), refer to
"Rotation (times)" in "History Data"
and set an appropriate value
depending on the work.
• The lower limit setting must not be
higher than the upper limit setting.
• Rotation (times) means the
number of rotations from when the
specified torque is detected after
the start of rotation to when the
clutch is activated.
[Default value]
• Upper limit OFF
• Lower limit OFF
[Setting value]
• Upper limit OFF Disable
ON
Enable / 0* times to 999 times
• Lower limit OFF Disable
ON
Enable / 0* times to 999 times
Entering the value with (*) will disable the function.
When the lower limit and the upper limit
are set to 3 and 5 respectively
