YA Gold Series User’s Manual
Thank you for purchasing our scale. Normal care and
proper treatment will provide for years of reliable
service. Please read all operating instructions carefully
before use. It may be necessary to calibrate the scale before the first
use.
PROPER OPERATION AND ENVIRONMENT
•Avoid any exposure to extreme heat or cold, your scale works better
when operated at normal room temperature. It is recommended to
allow the scale to acclimate to normal room temperature for at least
one hour before use.
•Allow your scale sufficient time to warm up. Usually 30-60
seconds to give the internal components a chance to stabilize before
calibration.
•Keep your scale in a clean environment. Dust, dirt, moisture,
vibration, air currents, and a close distance to other electronic
equipment can cause an adverse effect on the reliability and
accuracy of your scale.
•Handle your scale with care. Gently apply all items or samples to
be weighed onto the weighing surface. Although this scale is
designed to be quite durable, try to avoid rough treatment as this
may permanently damage the internal components.
•Avoid shaking, dropping, or otherwise shocking the scale. This is
a precision instrument and must be handled with extreme care.
•Only operate the scale on a stable, vibration free surface.
