TROUBLESHOOTING

The primary reason for inaccuracy or malfunction of the scale is due to low batteries or incorrect installation of batteries, incorrect or infrequent calibration, overloading the scale, or operating the scale on an unstable surface. Please keep in mind to maintain and operate your scale properly. The scale is a precision instrument and must be handled with the utmost care and caution.

PROPER OPERATION AND ENVIRONMENT

• Avoid any exposure to extreme heat or cold, your scale works better when operated at normal room temperature. It is recommended to allow the scale to acclimate to normal room temperature for at least one hour before use.
• Allow your scale sufficient time to warm up. Usually 30 – 60 seconds to give the internal components a chance to stabilize before calibration.
• Keep your scale in a clean environment. Dust, dirt, moisture, vibration, air currents, and a close distance to other electronic equipment can cause an adverse effect on the reliability and accuracy of your scale.
• Handle your scale with care. Gently apply all items or samples to be weighed onto the weighing surface. Although this scale is designed to be quite durable, try to avoid rough treatment as this may permanently damage the internal components.
• 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.
