General Maintenance and Care
• Avoid exposure to extreme heat or cold.
– Always allow your scale to acclimate to normal room
temperature before use.
• Keep your scale in a clean environment.
– Excessive dust, dirt, vibration, air currents, as well as close
proximity to other electronic equipment may have an
adverse effect on the accuracy and reliability of the scale.
• Handle the scale with care.
– Gently set all items to be weighed on top of the platform
and center them.
– Although this scale is designed to be quite durable, avoid
rough treatment as this may permanently damage the
internal components.
– Always avoid violent shaking and dropping.
– This is a precision instrument and should be handled
as such.
