ECS-B Floor Scale / EHP Bench Scale
1. INTRODUCTION
! 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.
! The floor scale’s platform is very heavy. Use appropriate lift equipment.
! The weighing platform must be installed on a foundation capable of safely supporting the
weight of the floor scale plus the weight of the maximum load.
! Do not operate in hazardous areas.
! Read and understand all operating instructions before using this product and 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 use.
! 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 use in heavy vibration or heavy airflow conditions. This also applies when the floor scale is
integrated into conveying systems.
