Servicing
Your seca scale leaves the factory with an
accuracy better than ± 0,4 / 0,2 %. To
ensure that this degree of accuracy is
maintained, the product must be carefully
set up and regulary serviced. Depending on
frequency of use, we recommend servicing
at intervals of 3 to 5 years. Please note that
a qualifi ed servicing agent should be used
for this. If you are in doubt, seca Customer
Service will give you more
