Un bon manuel d’utilisation

Les règles imposent au revendeur l'obligation de fournir à l'acheteur, avec des marchandises, le manuel d’utilisation Emerson Process Management MLT 5 and CAT 200. Le manque du manuel d’utilisation ou les informations incorrectes fournies au consommateur sont à la base d'une plainte pour non-conformité du dispositif avec le contrat. Conformément à la loi, l’inclusion du manuel d’utilisation sous une forme autre que le papier est autorisée, ce qui est souvent utilisé récemment, en incluant la forme graphique ou électronique du manuel Emerson Process Management MLT 5 and CAT 200 ou les vidéos d'instruction pour les utilisateurs. La condition est son caractère lisible et compréhensible.

Qu'est ce que le manuel d’utilisation?

Le mot vient du latin "Instructio", à savoir organiser. Ainsi, le manuel d’utilisation Emerson Process Management MLT 5 and CAT 200 décrit les étapes de la procédure. Le but du manuel d’utilisation est d’instruire, de faciliter le démarrage, l'utilisation de l'équipement ou l'exécution des actions spécifiques. Le manuel d’utilisation est une collection d'informations sur l'objet/service, une indice.

Malheureusement, peu d'utilisateurs prennent le temps de lire le manuel d’utilisation, et un bon manuel permet non seulement d’apprendre à connaître un certain nombre de fonctionnalités supplémentaires du dispositif acheté, mais aussi éviter la majorité des défaillances.

Donc, ce qui devrait contenir le manuel parfait?

Tout d'abord, le manuel d’utilisation Emerson Process Management MLT 5 and CAT 200 devrait contenir:
- informations sur les caractéristiques techniques du dispositif Emerson Process Management MLT 5 and CAT 200
- nom du fabricant et année de fabrication Emerson Process Management MLT 5 and CAT 200
- instructions d'utilisation, de réglage et d’entretien de l'équipement Emerson Process Management MLT 5 and CAT 200
- signes de sécurité et attestations confirmant la conformité avec les normes pertinentes

Pourquoi nous ne lisons pas les manuels d’utilisation?

Habituellement, cela est dû au manque de temps et de certitude quant à la fonctionnalité spécifique de l'équipement acheté. Malheureusement, la connexion et le démarrage Emerson Process Management MLT 5 and CAT 200 ne suffisent pas. Le manuel d’utilisation contient un certain nombre de lignes directrices concernant les fonctionnalités spécifiques, la sécurité, les méthodes d'entretien (même les moyens qui doivent être utilisés), les défauts possibles Emerson Process Management MLT 5 and CAT 200 et les moyens de résoudre des problèmes communs lors de l'utilisation. Enfin, le manuel contient les coordonnées du service Emerson Process Management en l'absence de l'efficacité des solutions proposées. Actuellement, les manuels d’utilisation sous la forme d'animations intéressantes et de vidéos pédagogiques qui sont meilleurs que la brochure, sont très populaires. Ce type de manuel permet à l'utilisateur de voir toute la vidéo d'instruction sans sauter les spécifications et les descriptions techniques compliquées Emerson Process Management MLT 5 and CAT 200, comme c’est le cas pour la version papier.

Pourquoi lire le manuel d’utilisation?

Tout d'abord, il contient la réponse sur la structure, les possibilités du dispositif Emerson Process Management MLT 5 and CAT 200, l'utilisation de divers accessoires et une gamme d'informations pour profiter pleinement de toutes les fonctionnalités et commodités.

Après un achat réussi de l’équipement/dispositif, prenez un moment pour vous familiariser avec toutes les parties du manuel d'utilisation Emerson Process Management MLT 5 and CAT 200. À l'heure actuelle, ils sont soigneusement préparés et traduits pour qu'ils soient non seulement compréhensibles pour les utilisateurs, mais pour qu’ils remplissent leur fonction de base de l'information et d’aide.

    2. AK Service Commands ASVC K0 S599 ExactNode Name Reading of LON variables of a network node Description: This command is an enlarged alternative to the S600 command. It may use the variables of all network nodes, even if they will not be analyz er modules. You only have to know the right node address (cf. S632). Syntax: ExactNode = Right network [...]

    Supplement S600: Access to LON network variables Access to network variables of an analyzer module. Notes: ☞ If a variable will contain several values (array) , you can access to these values by adding the corresponding number directly to the name of the variable. Example: LINYA = [31, 44, 54] LINYA1 = 31 LINYA2 = 44 LINYA3 = 54 ☞ The network v[...]
