American Weigh POCKET-PAL
Thank you for purchasing the American Weigh
POCKET-PAL series digital scale. Please read all
operating instructions carefully before use. This
electronic scale is a precision instrument. With normal
care and proper treatment, it will provide years of
reliable service. Never load the scale with more than
the maximum capacity. Overloading will permanently
damage it! Avoid any exposure to extreme heat
or cold. Your scale works better when operated at
normal room temperature. Always allow the scale to
acclimatize to normal room temperature for at least
one hour before use. Give your scale sufcient warm
up time. Usually 30-60 seconds before calibration to
give the internal components a chance to stabilize.
Keep your scale in a clean environment. Dust, dirt,
moisture, vibration, air currents and a close distance to
other electronic equipment can all cause an adverse
effect on the reliability and accuracy of your scale.
Handle with care. Gently apply all items to be weighed
onto tray top. Although this scale is designed to be
quite durable, try to avoid rough treatment as this
may permanently damage the internal sensor. 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.
