INSTALLATION & SERVICE TIPS
4-2
1. Inspect and Test
Always, always, inspect and test any component for your system before traveling to the job site. It is always
easier to solve a problem or ask a question when you have the tools and time to approach the task before
investing service and travel time.
2. Specifying Load Cells
When specifying load cells, be sure to use proper sizing techniques to determine capacity. To help you better
understand sizing techniques, we have included an article on determining microvolts per graduation, which
explains how to determine minimum readable signals and how to apply them.
3. Difference in Load Cell Construction
Understand that there are differences in load cell construction that determine their suitability for various
applications. Stainless steel construction is preferred for wet or corrosive environments, but stainless steel
alone is not always enough protection. Note that hermetic sealing is preferred over standard environmental
protection for use in washdown environments.
4. Altering Load Cell Cable
Be careful not to cut or alter the load cell cable attached to the load cell. This affects the calibrated signal
output and voids all manufacturer’s warranties.
5. Retaining the Calibration Certificate
Always retain the calibration certificate supplied with each load cell. Put this in your customer or job file
and use as a troubleshooting reference or replacement reference. On legal-for-trade scales where NTEP load
cells are required, the end user is required to keep these certificates for inspection by the Weights and
Measures inspector.
6. Service Situations
Approach all service calls prepared with a suitable ohmmeter, proper tools and replacement parts.
