I. Precautions before Using the Scale
Environment
The scale should always be used in an environment, which is free
from excessive air currents, corrosives, vibration, and temperature
or humidity extremes. These factors will affect displayed weight
reading.
DO NOT
install the scale:
Next to open windows or doors causing drafts or rapid
temperature changes.
Near air conditioning or heating vents.
Near vibrating, rotating or reciprocating equipment.
Near magnetic fields or equipment that generates magnetic
fields.
On an unstable work surface
In a dusty environment
In direct sunlight.
2
.
Protection in the transportation
When the initial use, please refer to the following drawing to
take off the protection screw. When the transportation will be
made, please install the protection screw on the machine to
avoid any damage sensitive components.
Leveling the Scale
The scale is equipped with a level indicator on the left bottom side
of the front panel and four adjustable leveling feet. Adjust the
leveling feet until the bubble appears in the center circle of the
indicator.
Turn on Scale
Do not turn on scale with anything on the platform. The switch is
located on the right side of the scale. The scale will start to count
down from nine to zero and will display the max. capacity of the
scale in the WEIGHT display. The scale is then ready for use.
Give a warm-up for 15~30 minutes before use.

IV. Description of the Connectors
Output ports
The scale is designed with two output ports:
1. Bidirectional RS-232, which can be connected to PC, printer,
and a control box to output 3 section control signal
2. 9-pins connector for a remote platform.
Position of the connectors
Both of the connectors are located at the left side of the bottom
housing.
