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.
