A non-automatic weighing instrument (NAWI) is a weighing instrument that requires the intervention of an operator during the weighing process, for example to deposit on or remove from the load receptor the load to be measured and also to obtain the result.
In the UK, this Directive is enforced by the National Measurement Office, part of the Department for Business, Innovation and Skills.
