Un bon manuel d’utilisation

Les règles imposent au revendeur l'obligation de fournir à l'acheteur, avec des marchandises, le manuel d’utilisation Elan ES381. 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 Elan ES381 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 Elan ES381 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 Elan ES381 devrait contenir:
- informations sur les caractéristiques techniques du dispositif Elan ES381
- nom du fabricant et année de fabrication Elan ES381
- instructions d'utilisation, de réglage et d’entretien de l'équipement Elan ES381
- 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 Elan ES381 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 Elan ES381 et les moyens de résoudre des problèmes communs lors de l'utilisation. Enfin, le manuel contient les coordonnées du service Elan 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 Elan ES381, 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 Elan ES381, 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 Elan ES381. 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.

    1 OVERVIEW The USBcount50 is an isolated dig ital pulse counter that has the following features: • Single channel pulse counter with BNC input and USB PC interface • Each USBcount50 can be stacked to increase channel count (each requires its own USB connection) 1 • 300V Cat II isolation between BNC ground and USB ground 2 This means that ther[...]

    2 ABOUT THE USBcount50 2.1 General The USBcount50 has been designed to allow a broad range of input frequencies and pulses to be measur ed. The input stage supply is programmable to allow the counter to work in circuits generating various Voh levels. Each USBcount50 can be used as an independent single channel counter but to enhance flexibility sev[...]

    2.3 Using More Than One USBcount50 2.3.1 S tacked Mode A unique feature of the USBcount50 architecture is that up to 4 devices 3 can be stacked to make a multi-channel instrument. In order to use a stacked configuration, you must purchase the stacking connector kit . This kit comprises 3 long lead connectors and 1 short lead connector as shown: 2.3[...]

  • Page 9

    Repeat this for all except the last counter to be stacked. For the last counter in the stack, do the same as above but use the short length connector. This time, the pins are shorter so they stop well inside the counter’s case. This counter MUST be the bottom counter in the stack . The reason for this is that if you use the long connector, the pi[...]

  • Page 10

    Start with the bottom counter. Hold it in one hand, and put the next counter on top of the 1 st , the same way around. Align the stacking connectors and when the stacking connectors are partly mated engage the front “P” shaped clip (BNC end) on the 2 nd counter into the “P” shaped slot on the 1 st counter. Now, bring the back edge “P” c[...]

    2.3.1.3 USB Connections For Stacked Configurations All stacked counters need a USB connection . A standard hub may be useful for multi-channel stacks to get enough USB ports. Each counter needs about 200mA. Plugging more than 2 counters into a hub will mean that the hub may need to be powered externally. Please refer to the hub’s documentation fo[...]

    2.3.1.5 Stacking Do’s And Don’ts • Do power off all counters (remove USB lead) before connecting and disconnecting counters from the stack • Don’t remove any counters from the stack while the software is running • Don’t remove any counters from the stack while any of them are powered • Don’t stack several counters and leave one or[...]

    2.3.2 Non-S tacked (MIS) Mode It is also possible to use multiple USBcount50s as independent instruments. In this mode, the counters are NOT connected together via the stacking interface 4 . This configuration is also termed Multi-Instrument mode or MIS mode. In MIS mode, each counter can use its own timebase setting, and each counter input will re[...]

    where “p” is the COM port number and “c” is the assigned channel number. For example, if you want to run 2 counters in MIS mode, use Window’s Device Manager to get the two COM port numbers for the two counters (see 3.2). Lets assume they are COM4 and COM5. Next, locate the USBcount50.exe program (normally under “Program FilesUSBcount50[...]

    2.4 Input Control 2.4.1 Input Supply The USBcount50 supports a progra mmable input supply via the slider control. Supplies from 1.50V to 5.00V are po ssible, and the slider control adjusts in 256 steps of 13.67mV per st ep. This range allows the user to match against common industry standard logic levels present in their circuit to be measured 6 . [...]

    2.5 Counter Modes 2.5.1 General In RUN mode, the counter continually display readings (assuming these is an input signal of course). Clicking ONCE, takes a single read ing and then places the counter into STOP mode, so that further readings cease. During measurements, the indicator in the reading panel changes colour depending on the state of the i[...]

  • Page 18

    Green means the reading is done. Red means the reading over-flowed i. e. external period too long or external frequency too high. Try a shorter internal period or lower internal frequency. If the counter waits for more than 2 seconds whilst in Period mode and no external signal has been de tected, the indicator will blink rapidly white-grey-white-g[...]

    2.5.2 Fr equency Mode The counter can be put into Frequency mode using the selection button shown below. Note too that clicking on a new period selection item will change to Frequency mode. In this mode of operation, the counter will use an internally generated gating period of 0.1s, 1s or 10s, to integrate (count) pulses that arrive at the input d[...]

  • Page 20

    2.5.3 Period Mode Period mode uses an internally ge nerated reference clock to time the period between two edges on the input waveform. It is selected as shown. The reference clock can be selected from 100MHz, 10MHz or 1MHz. The pair of edges that is timing is measured can be selected from: FALLING -> FALLING RISING -> FALLING FALLING -> R[...]

  • Page 21

    Period mode should be used if you have a single pulse or a slow input frequency. In the latter cas e, by timing the period from edge to edge allows a very accurate measurement of low frequencies by simply inverting the period measured . This is known as reciprocal mode. The software shows this reciprocal. Elan Digital Systems Ltd. 21 USBcount50 USE[...]
