FOIRE AUX QUESTIONS - UT693D Uni-T

Comment mesurer une tension continue avec l'UT693D ?

Tournez le sélecteur sur la plage DCV (V avec trait continu). Branchez les cordons : noir sur COM, rouge sur V/Ω. Placez les pointes sur les points de mesure. Lisez la valeur sur l'écran.

Comment tester la continuité d'un circuit ?

Placez le sélecteur sur la position de continuité (symbole sonore). Connectez les cordons comme pour une mesure de résistance. Si la résistance est inférieure à environ 30 Ω, un bip sonore retentit.

Comment remplacer la pile du multimètre ?

Éteignez l'appareil. Retirez le support arrière en dévissant les vis. Remplacez la pile 9V (type 6F22) en respectant la polarité. Refermez le compartiment.

Le multimètre n'affiche rien, que faire ?

Vérifiez que l'appareil est allumé (sélecteur sur une position de mesure). Testez ou remplacez la pile 9V. Si le problème persiste, consultez un réparateur agréé.

Quelle est la précision de l'UT693D ?

La précision varie selon la plage : ±(0.5% de la lecture + 2 digits) pour la tension continue. Reportez-vous à la notice pour les spécifications complètes.

Que signifie 'Data Hold' ?

La fonction Data Hold fige la valeur affichée à l'écran. Appuyez sur le bouton HOLD pour activer/désactiver. Utile pour relever une mesure dans un endroit difficile d'accès.

Peut-on mesurer des tensions supérieures à 600 V ?

Non, la tension maximale est de 600 V en catégorie CAT II. Ne dépassez jamais cette limite, risque de choc électrique et de dommage à l'appareil.

Comment nettoyer le multimètre ?

Utilisez un chiffon doux légèrement humide. N'utilisez pas de produits abrasifs ou de solvants. Évitez que de l'eau pénètre dans l'appareil.

Où télécharger la notice complète ?

La notice est disponible gratuitement au format PDF sur le site notice-facile.com. Vous pouvez la télécharger directement ou demander une traduction par email.

Quels fusibles de rechange utiliser ?

Utilisez un fusible de type F 250 mA / 250 V, de dimensions 5x20 mm. Pour le calibre 10A, un fusible 10A/250V peut être nécessaire. Vérifiez la notice.
