During Use |
| ||
Discharge static electricity from the weighing material. When | Material case | ||
weighing sample (plastics, insulator, etc.) could have a static | Charged | ||
charge, the weighing value is influenced. Ground the balance, and | sample | ||
Eliminate the static electricity by using an optinal static |
| ||
eliminator, | Grounding | ||
Or try to keep the ambient humidity above 45%RH at the room. | |||
Or use the metal shield case. |
| ||
Or wipe a charged material (plastic sample etc.) with the wet cloth. |
| ||
This balance uses a strong magnet as part of the balance |
| ||
assembly, so please use caution when weighing magnetic | Magnetic | ||
materials such as iron. If there is a problem, use the underhook on | material | ||
the bottom of the balance to suspend the material away from the |
| ||
influence of the magnet. | Draft | ||
Eliminate any temperature difference between the sample and the | |||
20°C 40°C | |||
environment. When a sample is warmer (cooler) than the ambient | |||
temperature, the sample will be lighter (heavier) than the true | Weighing Pan | ||
weight. This error is due to a rising (falling) draft around the sample. |
| ||
Make each weighing gently and quickly to avoid errors due to | Shock | ||
changes in the environmental conditions. |
|
Do not drop things upon the weighing pan, or place a sample on the pan that is beyond the balance weighing capacity. Place the sample in the center of the weighing pan.
Do not use a sharp instrument such as a pencil to press the keys.
Use your finger only.
Press the
key before each weighing to prevent
Calibrate the balance periodically so as to eliminate possible errors.
Take into consideration the affect of air buoyancy on a sample when more accuracy is required.
It is possible to check the reference card for principle operation.
Prevent foreign matter, such as powder, liquid and metal, from invading the area around the weighing pan.
Use the "breeze break" for a precision weighing.
3-3. After Use
Avoid mechanical shock to the balance.
Do not disassemble the balance. Contact the local A&D dealer if the balance needs service or repair.
Do not use organic solvents to clean the balance. Clean the balance with a lint free cloth that is moistened with warm water and a mild detergent.
