This instrument has been supplied in a safe condition. The present Operating Manual contains information
and warnings that shall be followed by the purchaser to ensure safe operation and to retain the instrument ina
safe condition.
— This specification is valid after the instrument has warmed up for 30 minutes (reference temperature 23 °C).
— Properties expressed in numerical values with tolerance stated, are guaranteed by the manufacturer.
Numerical values without tolerances are typical and represent the characteristics of an average instrument.
— Inaccuracies (absolute or in %) relate to the indicated reference value.
