Errata
This manual may contain references to HP or Hewlett-Packard. Please note that Hewlett-Packard's former test and
measurement, semiconductor products and chemical analysis businesses are now part of Agilent Technologies. To
reduce potential confusion, the only change to product numbers and names has been in the company name prefix: where
a product number/name was HP XXXX the current name/number is now Agilent XXXX. For example, model number
HP8648 is now model number Agilent 8648.
Ce manuel peut contenir des références à <<HP>> ou <<Hewlett-Packard.>> Veuillez noter que les produits de test et
mesure, de semi-conducteur et d'analyse chimique qui avaient fait partie de la société Hewlett-Packard sont maintenent
une partie de la société Agilent Technologies. Pour reduire la confusion potentielle, le seul changement aux noms de
reference a été dans le préfixe de nom de société : là où un nom de référence était HP XXXX, le nouveau nom de
référence est maintenant Agilent XXXX. Par example, le HP 8648 s'appelle maintenent Agilent 8648.
Diese Gebrauchsanweiseung kann Bezug nehmen auf die Namen HP oder Hewlett-Packard. Bitte beachten Sie, dass
ehemalige Betriebsbereiche von Hewlett-Packard wie HP-Halbleiterprodukte, HP-chemische Analysen oder HP-Test-
und Messwesen nun zu der Firma Agilent Technology gehören. Um Verwirrung zu vermeiden wurde lediglich bei
Produktname und - Nummer der vo laufende Firmenname geändert: Produkte mit dem Namen/Nummer HP XXXX
lauten nun mehr Agilent XXXX. Z.B, das Modell HP 8648 heißt nun Agilent 8648.
Questo manuale potrebbe contenere riferimenti ad HP o Hewlett-Packard. Si noti che le attività precedentemente gestite
da Hewlett-Packard nel campo di Test & Misura, Semiconduttori, ed Analisi Chimica sono ora diventate parte di
Agilent Technologies. Al fine di ridurre il rischio di confusione, l'unica modifica effettuata sui numeri di prodotto e sui
nomi ha riguardato il prefisso con il nome dell'azienda : dove precedentemente compariva "HP XXXX" compare ora
"Agilent XXXX". Ad esempio: il modello HP8648 è ora indicato come Agilent 8648.
Este manual puede hacer referencias a HP o Hewlett Packard. Las organizaciones de Prueba y Medición (Test and
Measurement), Semiconductores (Semiconductor Products) y Análisis Químico (Chemical Analysis) que pertenecían a
Hewlett Packard, ahora forman parte de Agilent Technologies. Para reducir una potencial confusión, el único cambio en
el número de producto y nombre, es el prefijo de la compañía: Si el producto solía ser HP XXXX, ahora pasa a ser
Agilent XXXX. Por ejemplo, el modelo HP8648 es ahora Agilent 8648.
