GW Series User/Service Manual INTRODUCTION General and Safety Information Risk of Electrical Shock: Disconnect all power sources before making cable connections to the floor scale platform or indicator. For use in dry environments only. Do not operate in hazardous areas. Read and understand all operating instructions before using this product. Keep this manual for future reference. Record the weight shortly after placing a load on the platform. After extended periods, the load cell’s output signal may result in a less accurate reading. Avoid extended exposure to extreme heat or cold. Optimum operation is at normal room temperature. See operating temperature range in the specifications table. Allow the scale to acclimate to room temperature before using. Allow sufficient warm up time. Turn the scale on and allow up to 2 minutes for internal components to stabilize before weighing. Electronic scales are precision instruments. Do not operate near cell phones, radios, computers or other electronic devices that emit radio frequencies that may cause unstable readings. This equipment has been tested and found to comply with the limits for a Class A digital device, pursuant to Part 15 of the FCC Rules. These limits are designed to provide reasonable protection against harmful interference when the equipment is operated in a commercial environment. This equipment generates, uses, and can radiate radio frequency energy and, if not installed and used in accordance with this manual, may cause harmful interference to radio communications. Operation of this equipment in a residential area is likely to cause harmful interference, in which case the user will be required to correct the interference at their own expense. Avoid using in heavy vibration or heavy airflow conditions. This also applies when the floor scale is integrated into conveying systems. Version 04.12 . 2.
