The underhook can be used for magnetic materials or density measurement. The built-in
underhook is revealed by removing the cap on the bottom of the balance. Use the underhook as
shown below.
Caution
Do not apply excessive force to the underhook.
When not in use, attach the cap to prevent dust from
getting into the balance.
Do not push the underhook upward
When turning the balance over, parts and weighing
matter in the weighing chamber will fall off. (Parts: the
weighing pan, pan support, breeze break ring, fine range
ring and dust plate )
Remove them first.
When the cap is removed, a weighing error may occur,
because of drafts entering into the internal portion of the
balance. Arrange the room condition.
