Protek RC PTK8269 User manual

Thank you for purchasing this 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 weight 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 sufficient 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.
