FOIRE AUX QUESTIONS - UT315A Uni-T

Comment mesurer une tension continue avec le UT315A ?

Tournez le sélecteur sur V⎓, insérez les sondes (noir dans COM, rouge dans VΩmA) et placez les pointes de test sur le circuit.

Que faire si l'appareil affiche 'OL' ?

OL signifie dépassement de la plage de mesure. Sélectionnez une plage supérieure ou vérifiez que les sondes sont correctement branchées.

Comment changer la pile du multimètre ?

Éteignez l'appareil, retirez les sondes, ouvrez le compartiment à l'arrière à l'aide d'un tournevis, remplacez les deux piles AAA 1,5V, puis refermez.

Le UT315A est-il adapté à la mesure de courant élevé ?

Oui, jusqu'à 10 A (courant AC/DC). Pour des courants supérieurs, utilisez une pince ampèremétrique. Ne jamais dépasser 10 A.

Comment tester la continuité d'un fil ?

Tournez le sélecteur sur le symbole ⏊ (diode/continuité). Si la résistance est inférieure à 50 Ω, un bip sonore retentit.

Puis-je mesurer la température avec cet appareil ?

Oui, avec une sonde thermocouple de type K (non fournie). Branchez-la dans les prises COM et VΩmA et sélectionnez le mode °C/°F.

Que signifie CAT II 600 V ?

Il s'agit d'une classification de sécurité. CAT II 600 V signifie que l'appareil peut être utilisé sur des circuits domestiques avec une tension nominale jusqu'à 600 V, mais pas sur des circuits de distribution.

Comment entretenir le UT315A ?

Essuyez le boîtier avec un chiffon doux et sec. Évitez l'humidité et les chocs. Retirez les piles si l'appareil n'est pas utilisé pendant plus d'un mois.

Où trouver les fusibles de rechange ?

Les fusibles sont des modèles spécifiques (souvent F 500 mA/250 V et F 10 A/250 V). Achetez-les auprès de revendeurs agréés Uni-T ou en magasin d'électronique.

Le rétroéclairage ne fonctionne pas, que faire ?

Vérifiez les piles ; une tension faible peut désactiver le rétroéclairage. Maintenez la touche LIGHT enfoncée pendant 2 secondes pour l'activer.

VI. Test Method Selection

Please select a proper test method from the following according to the actual situation. 1) Use short (S) probe to measure: The probe is mounted on the lesser. This method is applicable to vibration measurement in wide areas to acquire good response values, as shown below.

2) Use Long (L.) probe to measure: The probe is an accessory in the packaging box, which is mainly used in narrow or special object areas with quick response, as shown below.

Note: The long (L) probe is only suitable for low frequency measurement. When the frequency exceeds 1kHz in acceleration measurement, please replace it with the short (S) probe.
