USER WARNINGS RECOMMENDATIONS FOR THE PROPER USE OF WEIGHING INSTRUMENT Keep away from heat sources and direct sunlight Repair the instrument from rain (except special IP versions) Do not wash with water jets (except special IP versions) Do not dip in water Do not spill liquid on the instrument Do not use solvents to clean the instrument Do not install in areas subject to explosion hazard (except special Atex versions) - Page 6 CONNECTING SEVERAL CELLS IN PARALLEL: Connect several cells in parallel by using - if necessary - a watertight junction box with terminal box. The cell connection extension cables must be shielded, led individually into their piping or conduit and laid as far as possible from the power cables (in case of 4-wire connections, use cables with 4x1 mm minimum cross-section).

Do you have a question about the W100 and is the answer not in the manual?
Questions and answers
can w100 work on all areas aggregate, cement , addictive and water
The LAUMAS W100 can control batching for aggregate materials, cement, additives, and water by weight or pulses. However, the document does not specify compatibility with all types of these materials. It ensures that batching can start independently for aggregates while other scales are still in process, but no details are provided about material-specific limitations.
