1. INSTALLATION
Because of metrological legislation, installation/some
metrological parameter settings are limited to be done
by authorized personnel only. Do not attempt to change
any of the built-in parameters. Contact your dealer for
installation and technical assistance.
CAUTION:
This unit is legal for trade only when it is sealed (and/or
stamped) and bearing a serial number. Do not attempt
