BEFORE USING SCALE
Thank you for purchasing the Hornady® GS-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 acclimate to normal ro om temperature for at least one
hour before use.
Give your scale suffi cient 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.
