Proscale ProTouch IV User manual

Thank you for purchasing the Pro-Touch™ IV 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.
