•
This is to set the full-scale
tension (maximum
mechanical tension) and the
number of display digits.
For example, if desired to
have "50.0N" displayed,
select " 500 " and " × 0.1 ".
•
Zero adjustment should be
made with the tare weight of
the detection reel and
without material.
• If unable to make zero
adjustment, check the
system referring to pages 43
and 45.
• If the tension full scale is
changed, carry out the
zero/span adjustment again.
• Install the tension detectors
on both ends of the
detection reel as shown in
the left figure. For a short
detection reel, only one
tension detector may be
used. Use the following
screen to select one or two
tension detectors.

•
Suspend weight W (N).
The weight should be a
static load as close to the
full-scale tension value as
possible
(Should be between 1 to 1/3
of the full scale).
Stretch a string
in the center of
the roller.

Error Message
•
When, for example, a mass
of 10 kg is suspended,
multiply it by the
gravitational acceleration
(9.8) to make it 98N.
•
Do not alter the load during
the adjustment. Otherwise,
the system may not be able
to adjust or may generate
an error.
•
By the display unit setting,
the system shows the value
in the magnitude of "N" or
"×10N". When one tension
detector is used, the left
display shows zero. When
two detectors are used, the
left and right readings are
balanced.
•
When unable to adjust the
span, check the system
referring to pages 43 and
45.
•
If an error message
appears, the system can
not complete the
adjustment. Set the
system again.
• Initial setting completed.
The system setting screen
appears hereafter. Set the
parameters as necessary.
