Shop Tip:

Weighing Environment:

Two environmental factors affect the instrument’s stability dramatically--temperature and static electricity.

Temperature control is imperative. This includes both control of the room temperature and maintaining the internal temperature of the instrument. For best stability, maintain the room temperature within two degrees constantly (day and night). Leave the instrument plugged in and turned ON

Static electricity will cause erratic readings. Instruments should be operated on a static dissipating surface (anti-static mat). Operators should stand on anti-static floor covering. Avoid the use of plastic containers for items being weighed.
