SAFETY INSTRUCTIONS AND PRECAUTIONS
3-1. Safety Instructions on Intrinsically Safe Structure
Do not disassemble or modify the balance.
When determining the installation site, take the following into consideration.
Will explosive gases be generated? How often will they be generated?
Refer to “5. CONFORMING STANDARDS.”
A portion of the enclosure is non-conducting and, under certain extreme conditions,
may generate an ignition-capable level of electrostatic charges. The user shall
ensure that the equipment is not installed in a location where it may be subjected
to external conditions (such as high-pressure steam) which might cause a build-up
of electrostatic charges on non-conducting surfaces. Additionally, cleaning of the
equipment should be done only with a damp cloth.
Replace the batteries in non-hazardous areas.
As a power source, only the four “AA”, “LR6” or “AM3” alkaline 1.5 V batteries
listed below can be used.
DURACELL MN1500, ENERGIZER E91, Panasonic LR6(XJ)
All four batteries used in a single balance must be of the same type.
When replacing the batteries, be sure to prevent foreign materials from entering
the battery compartment.
3-2. Precautions on Installation
Do not install the balance
where corrosive gases are present.
Do not install the balance
where the balance will get wet or soaked with water.
Do not install the balance
where the balance will be exposed to direct sunlight,
drafts, vibration, large temperature fluctuations, condensation or magnetism.
Do not install the balance near air conditioners or heaters.
Use a solid weighing table to keep the balance level.
Level the balance by adjusting the leveling feet and confirm it using the bubble spirit level.
Allow the balance to reach equilibrium with the ambient temperature before use.
