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.
