3-2. Installing the Scale Unit
Notes
• Do not turn on the power before installing the scale unit.
• Do not take off the head holders, if possible, until immediately before securing the scale head.
Even if the head holders are removed, the approximate positional relationship of the scale and scale
head will be maintained. However, the plastic hook can come off if the scale head is forcibly twisted or
other excessive force is applied. If the plastic hook comes off , return the plastic hook back to its original
position before performing the installation.
Head holder
• Th e scale head will be damaged if the scale head is moved outside the eff ective length (ML). Th e scale
head must always be moved within the eff ective length.
• Install the scale unit so that the scale is on the upper side of the scale head.
If the upper side is not available, set it to face horizontally. (Fig. 3-2)
