4.3 Under-floor Measurement
This balance is provided with a hook designed for under-floor measurement. This lets you conduct
measurement with a lower pan or other device suspended from the hook. In case a sample does
not allow accurate measurement when placed on the measurement pan, such as in the presence
of a magnetic material or strong static electricity, use the following under-floor measurement
procedure.
(1) First, unplug the AC adapter. Fully open all windshield
doors and remove the measurement pan, pan base,
windshield ring, and floor plate. To detach the floor plate,
hold it by the sides with both hands and pull it up.
(2) Turn the balance down and lay it on its back.

(3) Loosen the screw of the hook cover and rotate the hook
cover 90 degrees around the screw.
(4) Retighten the screw.
Rotate the
cover around
the screw.

(5) Put the floor plate, windshield ring, pan base, and
measurement pan back in place, and close all the
windshield doors.
The balance is now ready for under-floor measurement.
Hook for under-floor
measurement
Cautions:
1. Since the device suspended (lower pan) from the hook is treated as a tare, measurement
equivalent to the full weighing capacity cannot be conducted. The measurable weight will
be as follows:
Measurable Weight = Weighing Capacity - Weight of Suspended Device
2. If you are not going to conduct under-floor measurement any soon, keep the hook cover
closed to minimize dust.
