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.
