Proscale PX User manual

Thank you for purchasing the PX 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 maximal capacity. Overloading will permanently damage it!
Avoiding 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 room temperature for at least one
hour before use. Give your scale su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 eect 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.
