SECTION 3.0 OPERATION
Follow the instrument's manual for correct power-up instructions.
The C3600P and C7200P Ton Container Scales are relatively simple devices. Once the operation of the
instrument is understood, the ton containers are simply placed on the rollers that are provided. Listed are
a few helpful points to follow when using Eagle Microsystems scales.
1. Always place the ton container in the approximate center of the scale
2. Place the ton containers on the scale. Do not drop them. Although the scale is designed to
withstand impact loads, care should be taken to avoid accidents.
