When an operator is static charged

If an operator’s clothes are static charged, especially in winter, unstable weight values.

Wear an anti-static wrist strap.

Errors due to air flow

Where the influence of ambient air flow is great such as: close to an air conditioner, door or passage way. Even very subtle air flow that is hard to be detected may influence the weighing operation.

Avoid those areas as a weighing site.

If weighing is to be performed in such an area, use a breeze break or take other appropriate measures.

it may be a cause for

Influence of the air flow makes the weight value unstable

Where the influence of heat or drafts is great Eliminate temperature differences between a sample and the environment.

When a sample is warmer (cooler) than the

ambient temperature, the sample will be	Draft				40 C

Do not touch the sample directly with your
hand. Use tweezers or other tools.

If you touch the sample, the same type
error described above will occur.

Do not perform weighing where it is exposed to direct sunlight. Weighing errors may occur due to sudden temperature change or drafts.

Where the influence of vibration is great, such as:

(1)Soft ground (2) Second or higher floor (3) Near center of a floor far from pillars (4) Seismic isolated structures (5) Near tall buildings.

In the areas listed above, the scale may yield unstable weight values on windy days or after an earthquake. Especially in case of (4) and (5), weight values may be unstable during and for a long period of time after strong winds or an earthquake.

Errors due to other causes Change in temperature or humidity

A sudden change in temperature or humidity can generate a draft and cause the balance to absorb or exude moisture, which leads to weighing errors.

Avoid sudden change in temperature or humidity.

Use an air conditioner to control the temperature or humidity.
